Dresses, Sets & Jumpsuits Size Guide
For dresses, matching sets and jumpsuits, bust and waist decide the size; the hip line matters most on a bodycon or a pencil skirt. Sizes run XS to 3XL.
These are body measurements based on standard US women's sizing (ASTM D5585 misses grade), not Inxiz garment measurements. Where a product page carries its own size table, that table is the one to follow.
Body measurements (inches)

| XS | 0-2 | 32-33 | 24-25 | 34.5-35.5 |
| S | 4-6 | 34-35 | 26-27 | 36.5-37.5 |
| M | 8-10 | 36-37.5 | 28-29.5 | 38.5-40 |
| L | 12-14 | 39-40.5 | 31-32.5 | 41.5-43 |
| XL | 16-18 | 42-44 | 34-36 | 44.5-46.5 |

How to measure
- Bust: around the fullest part of your bust, tape level, snug but not tight.
- Waist: around the narrowest part of your torso, usually just above the navel.
- Hips: around the fullest part of your hips and seat, roughly 8 in (20 cm) below your natural waist.
Keep the tape parallel to the floor and measure over your underwear rather than over clothes. If you can, have someone else hold the tape.
Fit notes
- A fitted bodice or a bodycon has little room to spare - take the larger size if you are between two.
- An A-line, a wrap or a tie waist forgives the hip measurement; go by bust.
- Some dresses are listed with a US numeric size (US 2 to US 16), a W size (US 16W to US 26W) or One Size. Follow that product's own table.
- Garment length is on the product page, because it changes with the cut - a midi on the same size can sit at two different points.
