Abaya sizing

Don't choose your abaya from one number

Amani's•16 min read•Updated November 07, 2026

The chart says 56, your usual clothes say medium, and the product photograph shows a dress that looks much wider than either label suggests. Before choosing a size, work out what those numbers are describing. Length, body measurements and finished garment dimensions answer different questions. Comparing them as though they were the same is where an apparently careful purchase can go wrong.

You do not need to turn shopping into pattern cutting. You need a measuring route you understand, a comfortable garment to compare where possible, and clear answers about the parts that matter to you. This guide uses invented charts and worked examples to show the process. None of the example dimensions is a specification for an Amani's product or a universal allowance for modest fit.

Keep the size decision separate from the question of how your body ought to look. The useful result is an abaya with the coverage, movement and outline you prefer. A number is information about a garment or chart, not an assessment of the person wearing it.

First ask what the chart measures

Read the headings and any note beneath the table. Does it describe the body the seller intends the size to fit, or the dimensions of the garment itself? Does a width mean a flat measurement across the front or a measurement around the whole garment?

A body chart helps relate your measurements to the seller's sizing system. A finished garment chart describes the item you will receive, subject to any stated measurement tolerance. Neither should be silently substituted for the other.

If the chart gives only a number beside bust, ask what that number means. A figure that seems surprisingly small could be a flat width; a larger figure could be a circumference or a finished dimension with considerable room. Guessing from which interpretation is more reassuring is not a reliable method.

Also establish the unit. Centimetres and inches must not be compared without conversion. Keep the original units in your notes so that a later calculation does not lose its meaning.

A clear question to the seller might be: “Does this chart show body measurements or finished garment measurements, and is the chest measured flat or all the way around?” That question can resolve more uncertainty than asking whether a size generally runs big.

At Amani's, a numbered abaya length is not your total height

Amani's familiar numbered abaya lengths, such as 52, 54, 56, 58, 60, 62 and 64, refer to shoulder-to-feet length in inches. Do not select the number by treating it as your full standing height or as a standard UK dress size.

Use the information for the particular product alongside that convention. Check width, sleeves and the design of the upper garment separately. A longer option does not automatically solve a tight upper arm, and a broad cut does not guarantee the right neckline.

Where another seller uses a different measuring route, follow that route when comparing its garment. An overhead style measured from the top of the head section is not directly comparable with a shoulder-based measurement. A separate skirt measured from its waistband is another dimension again.

Do not subtract a fixed number from your standing height to estimate garment length. Shoulder position, the chosen starting point and how the garment hangs make that a different question. A comparison taken from a comfortable existing garment can be more informative when the routes match.

Keep the conversion separate from the fit decision

One inch is exactly 2.54 centimetres; the National Institute of Standards and Technology's length reference gives the equivalent definition in millimetres. Multiply inches by 2.54 to obtain centimetres, or divide centimetres by 2.54 to obtain inches.

For example, 56 inches converts to 142.24 centimetres. Rounding that to about 142.2 centimetres may be convenient in a comparison note, but it does not make the measurement more precise than the way the actual garment was measured.

Length expressed in inches Mathematical equivalent in centimetres
52 132.08
54 137.16
56 142.24
58 147.32
60 152.40
62 157.48
64 162.56

This is a conversion table, not a recommendation by body height and not a substitute for an individual product's dimensions. A correct calculation can still be applied to the wrong measuring route. Establish what has been measured before using the converted number.

Write both the number and its meaning: for example, a stated finished shoulder-to-hem measurement, not simply “142”. That small habit makes later comparisons much clearer.

Body measurement and garment room are different things

The space allowed beyond a body measurement is often described as ease. New Mexico State University's pattern-alteration guidance explains that the amount depends on the design, fabric and fit preferences. Its example allowances concern fitted sewing projects; they are not a universal formula for choosing an abaya.

Use that distinction to understand a chart, not to impose one fixed amount of extra room on every garment. A loose woven outer layer, a stretch dress and a broad joined-sleeve design can have different relationships with the body.

Do not add an allowance to your body measurement and then present the result as your actual measurement. If the maker or chart already accounts for ease, you could end up adding it twice. Give the requested measurement accurately and describe your preferred fit separately.

Equally, do not assume a garment dimension equal to your body dimension provides the loose fit you want. The arithmetic may show no additional room at that point. Fabric stretch, construction and your preferences still need consideration rather than an automatic conclusion that the size will work.

A familiar garment can help you judge the kind of room you enjoy. It is a practical reference, not proof that every different cut with one matching number will feel identical.

Worked example: two charts that look similar

Imagine a person comparing two fictional listings. Listing A gives a chest figure of 100 centimetres and explicitly says it is a body-size guide. Listing B gives 58 centimetres and explicitly says this is a flat finished chest width on a simple closed garment.

Those numbers cannot be ranked as though 100 is simply larger than 58 in the same sense. One describes a body measurement; the other describes a distance across fabric. Before comparing fit, the shopper needs to understand the finished dimensions intended by Listing A and the measuring method used by Listing B.

For the simple, evenly laid-flat example in Listing B, twice 58 is 116 centimetres. If the relevant body measurement is 100 centimetres, the numerical difference is 16 centimetres. That calculation illustrates the difference between measurements; it is not a recommendation that 16 centimetres is the right allowance for you.

The calculation also does not tell you whether the shoulder, upper arm, neckline or hip area will fit. Nor should every flat width be doubled blindly: unusual panels, overlaps, shaping or a different measuring position may require clarification from the maker.

The sensible next step is to ask for the missing dimensions and compare a similar garment you already understand. A correct subtraction is useful, but it is only one part of the fitting decision.

Measure a comparison garment without changing its shape

Choose an abaya that fits comfortably for the role you are shopping for. A loose occasion garment may not be the best reference for a close-sleeved everyday piece, and a garment altered since purchase should be measured in its current form rather than remembered by its original label.

Lay it on a suitable flat surface and arrange it without stretching or pulling it into a larger shape. Use the same fastening arrangement specified for the new garment's measurement. Keep a tape measure straight along the stated route rather than following an unintended diagonal.

Record the dimensions you can compare meaningfully. Those might include length, a specified flat body width, sleeve measurement and cuff opening. Ask the seller where each measurement starts and ends when the description is unclear.

Take a photograph showing the tape and measuring points if it will help communicate a question. Keep it a garment photograph; there is no need to share personal body images to ask what a product chart means.

Note what you like and what you would change about this reference. “Comfortable through the body, but I would prefer more sleeve reach” is more useful than treating every dimension as an ideal to reproduce.

Worked example: the same length does not mean the same fit

Consider two fictional closed abayas compared with a familiar garment. All three are measured using the same stated routes, and all three have a broadly similar sleeve construction for the purpose of this example. These figures are invented to illustrate a comparison, not to recommend a size.

Finished measurement Familiar garment Option A Option B
Shoulder-to-hem length 142 cm 142 cm 142 cm
Specified flat body width 58 cm 60 cm 64 cm
Sleeve length on the agreed route 58 cm 58 cm 55 cm

Suppose the familiar garment has comfortable sleeves but you would enjoy a little more body room. Option A provides a wider listed body dimension while retaining the reference sleeve measurement. Option B is wider again, but its sleeve is shorter on the same route. Neither should be chosen only because its main size label sounds more generous.

The width difference between the familiar garment and Option A is 2 centimetres across the flat measurement. In the simple construction assumed here, doubling that difference gives 4 centimetres around the corresponding section. Do not describe that as merely 2 centimetres of additional circumference, and do not use the calculation for another construction without confirming the method.

There are still unanswered questions. The fabrics may behave differently, the lining may have its own fit, and the cuff openings have not been compared. The table narrows the enquiry; it does not establish that either option will feel comfortable or provide every feature you want.

A useful message to the seller could identify that missing information rather than asking which size is best in general. You might confirm the lining dimensions or cuff measurement, then assess whether the proposed garment serves the role the familiar one already fills.

Now change the example: imagine Option B has a dropped shoulder while the reference does not. The same sleeve-measuring description may no longer create a straightforward comparison of reach on the wearer. That is why construction belongs beside the numbers, not in a separate decision made after choosing a size.

Keep rounding from creating a false disagreement

A converted figure may contain more decimal places than a seller uses in a chart. Keep the unrounded calculation in your notes if useful, then read the seller's stated measuring method and any published allowance. Do not assume a neat chart value means every item has been specified to a fraction of a millimetre.

At the same time, do not invent a tolerance to explain away a difference. Ask which measurements the seller gives and how a concern should be checked. A photograph showing the tape along the agreed route is more informative than several measurements from different starting points.

If the question is simply that the garment matches its specification but you prefer another fit, describe that accurately. Clear records help distinguish a purchase that is unsuitable for your needs from a disagreement about what was supplied. Neither situation is improved by changing the figures to make the conclusion seem more certain.

Sleeve numbers need a starting point

A sleeve measured from a conventional shoulder seam is not being measured along the same route as one measured from the centre back or from another point near the neck. A dropped shoulder can also change where the visible sleeve begins.

Imagine two fictional garments each described as having a 55-centimetre sleeve. One measurement starts at the shoulder seam; the other begins at a different point in a joined sleeve-body construction. The matching figures do not establish matching reach.

Ask the seller for the route and compare a similar construction where possible. Do not add a shoulder figure to a sleeve figure using an assumed path and call the result the maker's sleeve length.

Check upper-arm room and the cuff separately. A wide wrist opening does not guarantee space where the elbow bends, and a long sleeve is not helpful if its cuff repeatedly covers the hand in a way you find inconvenient.

During a fitting, use the inner layer you expect to wear and bring your hands forwards. Notice where the garment pulls or rises. That is information about the complete sleeve arrangement, not a reason to keep choosing more length without looking at the cut.

Broad cuts need more than the largest available width

A butterfly or other broadly draped abaya may have a very generous flat measurement. Find out what that figure describes. The distance across the garment with its sides extended is not necessarily the same as usable room at a particular body point.

Look at the relationship between sleeve and body. Raise your hands during a try-on and see whether that movement lifts the lower garment. Then lower them and allow the folds to settle. Both positions matter.

For an online purchase, ask about the opening and sleeve arrangement rather than relying solely on an impressive width. A broad silhouette can still have a restrictive neck opening or an unsuitable cuff.

The guide to abaya cuts helps distinguish the constructions. Use it alongside measurements rather than expecting a single size label to explain every shape.

Length should be checked with the actual shoes

Choose the footwear for the garment's main use before settling its length. A hem that works with an occasional higher shoe may be awkward with the flats you wear most days. The comparison should reflect the outfit you will actually use.

Stand naturally rather than stretching upwards or leaning to inspect the tape. For a long measurement, help from another person can make the route easier to keep consistent. NMSU's measurement-preparation guidance also emphasises normal posture and recording measurements as they are taken.

During a try-on, walk and turn, checking the back edge as well as the front. A photograph taken while the hem is held slightly away from the floor does not establish practical clearance.

If a garment will be used in a different footwear arrangement for prayer, assess that use separately against the coverage guidance you follow. One outdoor length should not be assumed to answer every setting.

A shaped hem, a longer back or a border needs its own check. Ask about the longest point and any planned alteration. Shortening the centre front alone does not describe what will happen to the whole outline.

When your measurements sit between chart entries

Do not turn the decision into an automatic instruction to choose the larger number. First identify which measurement is between entries and what the chart means. A body chart and a finished garment chart require different interpretation.

Look at the full row for each option. A change that adds body width may also change the shoulder, sleeve or length. If one size solves one problem while creating several others, another cut may be more suitable.

Consider the intended layers and your preferred ease. Describe those to the seller with the relevant measurements. Ask for clarification about the actual garment rather than requesting a guarantee that a label will fit.

Do not use stretch as permission to choose a size that must remain under tension to provide ordinary movement. You may prefer a looser outline even when the material can physically extend further.

Where the available information cannot resolve the question, keep that uncertainty visible in the purchase decision. A reassuring product name, review or photograph does not replace the missing measurement.

Free size is a description to investigate

Ask which dimensions are fixed and which can be adjusted. A tie may change one opening without changing the sleeve or body width. Elastic can alter an opening's range without making every position equally comfortable.

Find out how the garment was measured. A relaxed width and a maximum stretched width tell different stories, and neither alone describes the feel during wear. Choose an arrangement that suits your preferences rather than the largest dimension the cloth can be pulled to.

For a set, ask about each component. The upper piece and lower garment can have different limits even when they share one size label. A comfortable top does not settle the waistband, rise or length of the accompanying piece.

Keep the questions practical: the face opening, sleeve reach, relevant width and the measurement route for length. A free-size label should not be treated as a universal promise or rejected without examining those actual details.

A message that gets you closer to an answer

Identify the product and the size you are considering. Ask whether the chart is body-based or garment-based, and which measuring route is used for the dimension causing uncertainty. Keep each question specific enough to answer.

For example: “I am comparing this abaya with one I already wear. Please confirm the finished shoulder-to-hem length and the point used for the flat chest measurement in size 56. Is the sleeve measured from the shoulder seam or another point?”

Where useful, add what needs to change: “My current garment is comfortable through the body, but its sleeves are shorter than I prefer over an inner top.” Do not silently alter the measurements to express that preference.

Keep the response with the listing and order details. If a seller provides a product-specific correction to a general chart, retain both so you understand which information you relied on.

You do not need to share unrelated personal information. The purpose is to understand the garment and the comparison, not to ask a remote seller to infer everything about fit from a body-shape label.

Do not promise an alteration before someone has assessed it

Separate a small adjustment from a change to the garment's underlying construction. A plain hem, a decorated border and a lined sleeve can involve different work. Ask a suitable alterations professional about the actual item.

Take the shoes and layers intended for the finished outfit. Explain the problem in measurable terms: too much length with these shoes, a cuff that covers the hand, or a closure that pulls while seated. Avoid a vague request to make the garment more flattering.

Ask what the proposed change affects elsewhere. Moving a cuff or shortening a lined garment can require more than altering the visible outer edge. Do not assume the original finish will remain identical after a substantial change.

Adding room is another question from removing cloth. Available seams, panels and construction matter. Buying an unsuitable size in the hope that a tailor can create missing space is not the same as confirming a realistic adjustment beforehand.

Resolve purchase and return questions before irreversible work. Keep any alteration record with the new finished measurements so a future comparison does not rely on a size label that no longer describes the garment.

What to check when the parcel arrives

Confirm the item and selected option before measuring it. Read any supplied care and try-on information, and keep the garment in an appropriate condition while deciding whether it works for you.

Use the seller's measurement route when comparing it with the stated figures. Do not measure a different point and immediately treat the difference as an error. If a tolerance is provided, read what it applies to; do not invent a universal tolerance yourself.

Try the complete outfit with familiar layers and shoes. Sit, reach, turn and walk. Note specific issues rather than adjusting everything repeatedly until the standing photograph appears satisfactory.

Distinguish a measurement discrepancy from a preference. A sleeve can match the published dimension and still be shorter than you enjoy. A garment can also differ from an agreed specification. Clear descriptions make those conversations easier to handle.

Do not use an unapproved hot wash or forceful stretching as a sizing experiment. Care is not a controlled alteration process. Settle the suitability question and follow the garment's actual instructions.

Keep a measurement card you will understand later

Record the date, the garment and the units. Keep body measurements, finished garment measurements and preferred changes in separate fields. That prevents an added allowance or converted figure from being mistaken for an original measurement.

Include how the length and sleeve were measured, the shoes used during the fitting and the main inner layer. Those details explain why a garment worked in one combination and not another.

Update the note after alterations or a genuine change you have verified. Do not assume every future product from the same range uses an unchanged cut. Use the card as a reference, not a reason to stop reading the new listing.

The complete abaya guide connects sizing with fabric and everyday use. The chart-reading habit is simpler: establish what each number measures, compare like with like and let the fitting test the result.

A size chart cannot guarantee a perfect garment. Read accurately, it can remove avoidable uncertainty and give you much better questions to ask. Choose the clothes that work for your body and routine, rather than trying to fit yourself into an unexplained number.
