Our collection uses several sizing systems, because different styles are cut in different ways. This guide explains the labels you will see on product pages and which chart applies. The product page always shows the chart for that item, so use it first.
Numeric sizes like 1/25 and 3/26
Women's jeans and bottoms are often labelled with two numbers, such as 1/25 or 3/26. The first number is the US junior size and the second is the waist size in inches. Some styles show just the waist number, such as 26.
| Size | US junior | Waist | Hips | EU | UK |
|---|---|---|---|---|---|
| 24 | 0 | 24 | 34 | 32 | 4 |
| 25 | 1 | 25 | 35 | 34 | 6 |
| 26 | 3 | 26 | 36 | 36 | 8 |
| 27 | 5 | 27 | 37 | 38 | 10 |
| 28 | 7 | 28 | 38 | 40 | 12 |
| 29 | 9 | 29 | 39 | 42 | 14 |
| 30 | 11 | 30 | 40 | 44 | 16 |
| 31 | 13 | 31 | 41 | 46 | 18 |
Rise is 7.75 inches on standard bottoms and 10.5 inches on high-waisted jeans.
Letter sizes: XXS to XXXL
Letter sizes are used for tops, skirts, dresses and many unisex strap pants, but the measurements behind them differ by category. Some unisex strap pants are sold in numeric waist sizes (for example 24 to 40) instead; use the chart on their product page. A women's skirt in size S fits a 26–28 inch waist, while a unisex strap pant in size S has a 33-inch fully extended waistband because it is cut on men's sizing. Always check the chart on the product page. See how to size strap pants.
Plus sizes
Plus size tops, outerwear and dresses use 0X to 4X:
| Size | Equivalent | Bust |
|---|---|---|
| 0X | 12 | 39 |
| 1X | 14/16 | 42 |
| 2X | 18/20 | 46 |
| 3X | 22/24 | 50 |
| 4X | 26/28 | 54 |
Plus size bottoms use numeric sizes from 10 to 28, with waist measurements from 30 to 48 inches and hips from 39 to 57 inches. On product pages these appear as, for example, 14 (Plus). Browse plus size styles.
