Chanel Dress Sizing for Preloved Buyers
Share
Quick answer: Chanel dresses use French sizing: FR 34 = US 2 (IT 38, UK 6), FR 36 = US 4, FR 38 = US 6, FR 40 = US 8, FR 42 = US 10 — with a FR 38 fitting roughly an 88 cm bust and 70 cm waist. Because fit changes completely with the silhouette (a fitted sheath and a loose shift in the same size feel like different garments), convert the label first, then trust the flat measurements over the number.
A Chanel dress can be the easiest preloved piece to fall in love with and the hardest to size correctly, because the fit changes completely with the silhouette. A fitted sheath and a loose shift in the same labelled size will feel like different garments. This guide gives you the Chanel dress size conversions, explains how each shape fits, and shows you how to measure so a dress that looks perfect online actually fits when it arrives.
Convert the label, then trust the measurements over the number.
Key takeaways
- Chanel uses French sizing; a single number on the label is almost always the FR size.
- FR 38 is roughly a US 6, UK 10, IT 42, a women's medium.
- Silhouette matters more than the number: sheaths run fitted, shifts and A-lines run forgiving.
- Always check flat bust, waist, and hip measurements before buying, especially for vintage.
Chanel dress size conversion chart
Chanel labels its ready-to-wear in French sizes, so the first step is converting that number to whatever you usually shop in. Here's how Chanel dress sizes line up across systems, with approximate body measurements as a sanity check.
| FR (Chanel) | IT | US | UK | Bust | Waist |
|---|---|---|---|---|---|
| 34 | 38 | 2 | 6 | ~80 cm | ~62 cm |
| 36 | 40 | 4 | 8 | ~84 cm | ~66 cm |
| 38 | 42 | 6 | 10 | ~88 cm | ~70 cm |
| 40 | 44 | 8 | 12 | ~92 cm | ~74 cm |
| 42 | 46 | 10 | 14 | ~96 cm | ~78 cm |
| 44 | 48 | 12 | 16 | ~100 cm | ~82 cm |
| 46 | 50 | 14 | 18 | ~104 cm | ~86 cm |
The quick mental maths: IT = FR + 4, and US = FR − 32. A Chanel FR 38 dress is an IT 42, a US 6, and a UK 10. For the full breakdown across categories, see our Chanel size guide.
How Chanel dresses fit by silhouette
This is where dresses differ from jackets: the same FR size fits differently depending on the cut. Read the shape before you trust the number.
- Sheath and bodycon: cut close to the body, so they run the smallest. If you're between sizes or carry curves, size up.
- Shift and A-line: looser through the waist and hip, the most forgiving shapes and usually true to the chart.
- Tweed dresses: structured with little stretch, so the waist and hip measurements matter most. Treat them like a jacket.
- Pleated and drop-waist: forgiving on the waist but check the hip and shoulder, which set the real fit.
Measure flat to be sure
The most reliable way to size a dress online is to compare it against one you already own and love. Lay your dress flat, zipped, and measure these points, then match them to the listing.
- Bust: armpit to armpit across the front, then double it.
- Waist: the narrowest point flat, doubled.
- Hip: about 20 cm below the waist, flat, doubled.
- Length: from the highest shoulder point to the hem.
For a fitted dress, the waist is the make-or-break number. For anything that skims the body, the hip matters just as much. Every Reemawy listing includes these flat measurements alongside the size label so you can compare directly.
Vintage Chanel dresses run smaller
Sizing has shifted over the decades, so a vintage FR 40 often fits closer to a modern FR 38. Older dresses can also have firmer, less forgiving fabrics and smaller armholes. Never assume your current size carries straight back to a 1990s piece, and when a vintage dress sits between sizes, size up and tailor down.
What can be altered on a Chanel dress
Some adjustments are simple; others aren't worth the risk on a couture piece.
- Usually fine: taking in the waist, shortening the hem, minor strap adjustments.
- Harder: letting out a fitted dress (limited seam allowance) and altering the bust or shoulders on a structured style.
Buy for the bust and shoulders, plan only light tailoring at the waist and hem, and use a specialist for anything involving the lining or trim.
Frequently asked questions
What size is a Chanel 38 dress?
A Chanel size 38 dress is a French size, equal to roughly a US 6, UK 10, and IT 42, a women's medium, with an approximate bust of 88 cm. Because fit varies by silhouette, always confirm against the dress's flat measurements.
Do Chanel dresses run small?
It depends on the cut. Fitted sheath and tweed styles run small and close to the body, while shift and A-line shapes are more forgiving. Vintage dresses also tend to run smaller than modern ones, so rely on measurements rather than the label alone.
How do I measure a Chanel dress for fit?
Lay the dress flat and zipped, then measure bust (armpit to armpit, doubled), waist (narrowest point, doubled), hip (doubled), and length from shoulder to hem. Compare those four numbers to a dress you already own that fits well.
Can a Chanel dress be altered?
Taking in the waist and shortening the hem are usually straightforward. Letting a fitted dress out is limited by seam allowance, and bust or shoulder changes on structured styles are difficult. Use a tailor experienced with couture fabrics and linings.
