Measurements are body measurements in cm from a major UK retailer’s women’s chart. Other brands may differ by 1 to 3 cm per size.
How to measure for your dress size
- Bust: measure around the fullest part, keeping the tape level under your arms. Wear a non-padded bra.
- Waist: measure around your natural waist, the narrowest part above your belly button.
- Hips: stand with your feet together and measure around the fullest part of your hips and bottom.
- Keep the tape snug but not tight, and measure over underwear rather than clothes.
UK, EU and US dress size conversion
UK sizes are 28 lower than EU sizes and 4 higher than US sizes for women’s clothing: a UK 12 is an EU 40 and a US 8. Australian sizes usually match UK sizes.
If you are between sizes
Go by your largest measurement for fitted styles, such as a sheath dress, where you cannot let it out. For stretchy fabrics, wrap dresses or styles with a defined waist you may suit the smaller size. Read the retailer’s fit notes and reviews, because brand sizing varies.
Petite and tall ranges use the same bust, waist and hip measurements but change the length of the body, sleeves and skirt. If you are under about 5 ft 3 in or over about 5 ft 10 in, check those ranges for a better fit.
