Chanel Size Guide: FR, IT, US & UK Conversion (2026)

Quick answer: Chanel labels its ready-to-wear in French (FR) sizes, which run smaller than US sizing. The conversions are FR 34 = IT 38 = US 2 = UK 6 (XS); FR 36 = IT 40 = US 4 = UK 8 (S); FR 38 = IT 42 = US 6 = UK 10 (M); FR 40 = IT 44 = US 8 = UK 12 (L); FR 42 = IT 46 = US 10 = UK 14 (XL). The shortcuts: US size = FR − 32 and IT size = FR + 4. So a Chanel FR 38 jacket is a US 6 (medium). Chanel runs true-to-small, and tailored or vintage tweed often fits a half-size tighter, so always check the listing’s flat measurements — not just the label — before buying preloved.

Buying preloved Chanel is one of the smartest ways to own the house's iconic tweed, but it comes with one recurring headache: sizing. Chanel labels its ready-to-wear in French (FR) sizes, many pre-owned listings show Italian (IT) numbers, and you probably think in US or UK. Get the conversion wrong and a jacket that looked perfect arrives unwearable. This guide gives you the exact Chanel size conversions, explains how to read a preloved label, and shows you how to nail your fit before you buy.

Chanel clothing size conversion chart (women's ready-to-wear)

Chanel uses the French sizing system as its base. Here is how French sizes line up with Italian, US, UK, and standard letter sizes for women's ready-to-wear:

FR (Chanel)	IT	US	UK	Letter
34	38	2	6	XS
36	40	4	8	S
38	42	6	10	M
40	44	8	12	L
42	46	10	14	XL
44	48	12	16	XXL
46	50	14	18	3XL

The quickest mental shortcut is IT = FR + 4 and US = FR − 32. So a Chanel FR 38 is an IT 42, a US 6, and a UK 10, a classic medium.

How to read a preloved Chanel size label

At Reemawy we list every garment in the format "FR 38 (IT 42 • M)" so you never have to do the math. But when you shop preloved elsewhere, you may see only one number, and older pieces can be labelled differently:

• Single number: a lone "38" on a Chanel label is almost always the French size (so FR 38 = US 6), not Italian.
• Vintage pieces: pre-2000s garments sometimes run slightly smaller than the modern chart, size up half a step if you're between sizes.
• No size tag: common on altered or very old garments. In that case, flat measurements are the only truth, see the next section.

Why measurements matter more than the tag

Chanel's fit has shifted across decades and collections, and preloved garments may have been tailored by a previous owner. The size on the label tells you what Chanel intended; the flat measurements tell you what will actually fit you today. Before buying, measure a garment you already own that fits well and compare these key points:

• Bust / chest: measured flat, armpit to armpit, then doubled.
• Waist: narrowest point, flat, doubled.
• Shoulder: seam to seam across the back, critical for structured tweed jackets, which can't be let out at the shoulder.
• Sleeve & length: Chanel jackets are often cropped, so check the back length.

Every Reemawy listing includes flat measurements alongside the size label for exactly this reason. If a measurement isn't shown, message us before you buy.

Fit notes by category

Chanel jackets & tweed

The famous Chanel tweed jacket is cut close and structured. The shoulder is the make-or-break measurement, it's the one area a tailor can't easily adjust. If you're between sizes, choose by shoulder width first, bust second. Many buyers size up one step from their usual ready-to-wear for comfortable layering. Browse current pieces in Reemawy Clothing.

Chanel dresses & skirts

Dresses follow the chart above but vary by silhouette, a fitted sheath runs smaller than an A-line. Skirts are best chosen by waist measurement, since Chanel waistbands have little stretch. For tweed skirts, confirm the hip measurement too.

Chanel tops & knitwear

Knit and jersey tops are the most forgiving and usually true to the chart. Cropped Chanel tops run short by design, so check the front length if you prefer more coverage.

Buying the right size in preloved Chanel: a 4-step checklist

1. Convert the label using the chart above so you're comparing like for like.
2. Compare flat measurements to a garment you already own and love.
3. Prioritise the unalterable points, shoulders on jackets, waist on skirts.
4. Check the era & condition, vintage runs smaller; confirm no prior alterations.

Frequently asked questions

What size is a Chanel 38?

A Chanel size 38 is a French size, equal to Italian 42, US 6, and UK 10, a women's medium.

Does Chanel run small?

Yes. Chanel uses French sizing, which runs about one size smaller than US sizing, and structured tweed jackets are cut close. Many buyers size up one step.

How do I convert Italian Chanel sizes to US?

Subtract 36 from the Italian number: IT 42 − 36 = US 6. Equivalently, IT = FR + 4 and US = FR − 32.

Are vintage Chanel sizes different from modern ones?

Slightly. Pre-2000s pieces can run a half-step smaller than the current chart, so rely on flat measurements for vintage garments.
