Which size should I choose for women's clothing?
On Opla, a women's clothing size is both a letter and a size number. Pick the one on the label: both mean the same size.
Letter | UK size | French size |
|---|---|---|
XXS | 4 | 32 |
XS | 6 | 34 |
S | 8 | 36 |
M | 10 | 38 |
L | 12 | 40 |
XL | 14 | 42 |
XXL | 16 | 44 |
3XL | 18 | 46 |
4XL | 20 | 48 |
5XL | 22 | 50 |
6XL | 24 | 52 |
7XL | 26 | 54 |
8XL | 28 | 56 |
Beyond that, UK sizes 30, 32 and 34 (French 58, 60 and 62) have no letter.
Display: on all women's clothing (dresses, tops, trousers, skirts, coats…), the size shows both, for example « UK 8 (S) ». Searching for S finds the same items.
Buying
- A garment in UK 10 and a garment in M are the same size.
- Fit varies from brand to brand: read the description (measurements, the seller's advice). If in doubt, ask the seller in a message before buying.
Selling
- Pick the size on the label. Pick « UK 8 (S) », « UK 10 (M) »… directly: if the label only shows a letter or a number, the table gives the other one.
- If the item runs small or large, say so in the description.
Special cases
- Jeans: a US size (W26, W28…) is a waist measurement. Put it in the description.
- Bras: they have their own grid (85B, 90C…).
- Shoes, men's and kids': separate grids, not covered by this table.
