Women's Leather Jacket Size vs Dress Size: What to Order

Your dress size gets you close, but your leather jacket size should be chosen by your bust measurement, then adjusted for the cut and your shoulders. As a rough guide, US dress sizes 0 to 2 start at XS on our women's chart, 4 to 6 at S, 8 to 10 at M, 12 at L, 14 at XL and 16 to 18 at 2XL, taking the larger option on slim cuts you plan to layer under.

The reason is simple: dress sizes drift from brand to brand, while a leather jacket is cut to a fixed bust measurement and has very little give. Below is the table we use with customers, the measurements that actually decide your size, and when made to measure is the better call.

Why your dress size is only a starting point

The US has no mandatory sizing standard for women's clothing; the old government system became voluntary in 1970 and was withdrawn in 1983, so each brand sets its own chart. The history of US standard clothing size shows how vanity sizing pushed the numbers down over the decades. Compare two charts for the same dress size and the bust can differ by an inch or more, which on most charts is a whole size.

Your dress size is also set by whichever part of you is hardest to fit. If you are pear-shaped, it is probably decided by your hips. If you have a fuller bust, it is decided by your bust. A jacket works differently. It hangs from your shoulders and has to close across your bust, so those two measurements choose the size, and your hips only come into play on styles long enough to cover them.

Leather also doesn't forgive a guess the way stretch fabric does. A knit top can stretch an inch to hide the wrong size. A leather panel has little give across its width, and the woven lining inside has almost none. Leather does relax as you wear it, mostly at the elbows and across the back as it takes your shape, but it will not add a size. That's why we size from a tape measure, not a label.

Leather jacket size vs dress size: a starting table

The bust figures below are typical of US retail size charts; the store you usually buy from may be an inch either way. The last column refers to our women's chart, where each size fits one bust measurement and steps up 2 inches at a time: XS fits 32 inches, S 34, M 36, L 38, XL 40, 2XL 42, 3XL 44 and 4XL 46. Where a dress size falls between two of those, you'll see two options.

Look at what happens from size 12 upward. Many stores label 12 to 14 as Large and 16 to 18 as XL, but on a chart sized strictly by bust, a 40-inch bust is an XL and a 43-inch bust is a 2XL or 3XL. If you wear a 14 and order the L you buy in tops, the jacket will probably close, but it will pull across the bust and leave no room for a sweater. That gap between letter labels and real measurements is behind a lot of the complaints you read about sizing, and our guide on whether leather jackets run small goes into it in more detail.

Measure first: the numbers that decide your size

Five minutes with a soft tape beats any conversion. Wear a thin top, stand relaxed and keep the tape level and snug without pulling it tight. Our size guide has the full chart in inches and centimeters.

1. Bust. Around the fullest part, with the tape straight across your back. This picks your row on the chart.
2. Shoulders. Across your back, from the edge of one shoulder bone to the other. Compare it with the shoulder column for the size your bust picked. The shoulder steps up only about half an inch per size, so if yours lands two or more sizes away, read the made-to-measure section below.
3. Sleeve. From the top of your shoulder, down the outside of a relaxed arm and over the elbow to the wrist bone.
4. Waist and hips. These only decide the size on belted and peplum styles and on anything long enough to cover your hips, such as a trench coat or a longline blazer.

A detail from the cutting table explains why shoulders matter so much. When a pattern is graded from one size to the next, every piece grows a little: the fronts, the back, the sleeves and the collar. Going up a size for your bust therefore also widens the shoulders and lengthens the sleeves, whether you need it or not. If your bust and shoulders land on the same row, a standard size will fit well. If they land two rows apart, no standard size will fit both, and that is the classic case for made to measure. If your bust is the larger number, our guide to choosing a leather jacket for a large bust covers it step by step.

How the cut changes the size you order

The same bust measurement can point to different sizes depending on how much room a style is cut with. Most product pages list a Fit line in the specifications, such as slim biker fit, relaxed bomber fit or tailored. Use it with these rules.

Slim biker and moto jackets

These are cut closest to the body, usually with a higher armhole and a shorter body. Order the size your bust gives you. A new biker should feel snug zipped over a T-shirt or thin knit, with no strain at the zip and no pulling across the back. If you know you'll wear a chunky sweater under it, that is the one case for going up a size, accepting that the shoulders and sleeves grow too.

Relaxed bombers

A bomber already has room in the body for a layer, usually gathered at a ribbed cuff and hem, so order your measured size. Sizing up a bomber is the most common mistake we see: the hem drops below the hip, the shoulders slide off, and the sleeves bunch at the wrist.

Tailored blazers

Here the shoulders lead. The shoulder seam should sit on the edge of your shoulder bone, and the sleeve should end where a little of your blouse cuff can show. Pick the size whose shoulder measurement matches yours, then check that the front buttons over a blouse without pulling into an X.

Coats and longline styles

Anything that reaches below your hips has to clear them when you walk and sit. If your hips are your largest measurement, choose the size that fits them, or go made to measure so the top half stays fitted.

A 6-step fit check when your jacket arrives

Try it on indoors, over the top you'll actually wear, and keep the tags on until you're sure. Standard sizes can be returned within 30 days of delivery as long as the jacket is unworn with its tags attached.

1. Close it fully. The front should lie flat. Ripples across the bust or a zip that bows outward means it's too small. Loose folds of leather at the sides mean it's too big.
2. Find the shoulder seam. It should sit on the edge of your shoulder bone, not hanging past it and not creeping toward your neck.
3. Reach forward. Stretch both arms out as if to hug someone. Some tension across the back is normal in a new leather jacket; a seam that feels close to splitting is not.
4. Check the sleeves. With your arms relaxed, they should end just past the wrist bone. Bend your elbow and the cuff should not ride far up your forearm.
5. Raise your arms. On a fitted cut the hem lifts a little. If the whole jacket rides up and the collar pulls back against your neck, the armholes are too tight or the body is too short.
6. Sit down. For coats and longer jackets, check that the hips and hem don't strain or pull open when you sit.

A jacket that passes all six but feels stiff is fine, because leather softens with wear. A jacket that fails steps 1 to 3 won't fix itself. If you land in the middle, our article on what to do when you're between sizes in a leather jacket walks through the trade-offs.

When to skip the chart and go made to measure

Made to measure means we cut your jacket from your own measurements instead of a standard pattern. It is worth it when:

• your bust and shoulders land two or more sizes apart on the chart;
• your hips are much larger than your bust and you want a long coat;
• your arms or torso are noticeably long or short for your size;
• you need a size below XS or above 4XL, since we make up to 8XL to measure.

To order, choose "Customise Size (made to measure)" on the product page, then email info@whiteburaq.com with your order number and your measurements: bust, waist, hips, shoulders, sleeve and the jacket length you want. In our workshop the pattern is adjusted before any leather is cut. The front and back panels are reshaped for your bust and waist, the shoulder width and armhole are set from your shoulder measurement, and the sleeves and body are lengthened or shortened. The cutter then lays each piece on the hide, keeping the fronts on the most even part of the skin, and the jacket is stitched, lined and finished by hand. It ships within 3 to 7 business days, and express delivery then takes 3 to 5 business days in the US and 5 to 8 elsewhere. You'll find the details on our made-to-measure page.

One thing to weigh before you choose it: made-to-measure, custom and personalized pieces are final sale, because they are cut for one person. Measure twice, and if you're unsure, email a photo of the tape on your body so it can be checked before cutting starts.

FAQ

I wear a size 10 dress. What size leather jacket should I get?

A US size 10 usually means a bust of about 37 inches. On our women's chart that sits between M (36) and L (38). Take M for a close biker fit over a T-shirt, or L if you want room for a knit. Measure to be sure, because your size 10 may not match another store's.

I'm a UK 12. What size is that in US sizing?

UK dress sizes run four numbers above US sizes, so a UK 12 is about a US 8, which usually starts at M on our chart. Our UK/EU letter sizes are one step above US letters, so check which column you're reading. Our leather jacket size conversion guide covers US, UK and EU sizing in full.

Do women's leather jackets fit differently from men's?

Yes. Women's styles are cut with a shaped waist and follow their own size chart, separate from the men's. If you prefer a looser, boyfriend-style line, choose one size up in a women's style. Shopping for a man instead? Our guide to leather jacket size vs suit size answers the same question for menswear.

Can I return a leather jacket if the size is wrong?

Standard sizes from XS to 4XL, including made-to-order ones, can be returned within 30 days of delivery if they are unworn with tags attached. Made-to-measure, custom and personalized pieces are final sale.
