Dress Size Converter
Convert a dress size, or enter bust, waist and hips to see which size each measurement needs — fitted dresses have to fit the largest.
Your result will appear here.
How to measure
- Measure bust, waist and hips as described in the clothing size converter, wearing the underwear you will wear with the dress.
- For wrap, A-line or stretch dresses the bust usually matters most; for sheath and bodycon dresses, all three matter.
Example: bust 84 cm (UK 8), waist 70 cm (UK 10) and hips 100 cm (UK 12) means a fitted dress in UK 12, possibly taken in at the bust.

FAQs
My bust and hips are different sizes. What should I buy?
Buy for the larger measurement and have the other area taken in. Separates or wrap dresses are easier when your measurements are two or more sizes apart.
Is a UK 10 the same as a US 10?
No. A UK 10 is about a US 6 and an EU 36.
Are Italian sizes smaller?
The numbers are higher, not the garments smaller: Italian sizes run 6 numbers above EU/German, so an IT 42 matches an EU 36.
