Navy Polka Dot Wrap Midi Dress

For dresses, matching sets and jumpsuits, bust and waist decide the size; the hip line matters most on a bodycon or a pencil skirt. Most of these styles run S to XL, many also offer XS, and 2XL and 3XL sit on a smaller group; a handful of dresses go higher still. Check the size list on the product page.

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)

Body measurements (cm)

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.
• A few dresses are sold as One Size, and ten run in extended sizes from 4XL to 10XL. Some size tables map the letter size to a US numeric or W size instead - 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.
