Dress Size Calculator for Every Silhouette
This dress size calculator handles the silhouette problem in one form: bodycon, A-line, sheath, and shift dresses all fit the same body differently. Enter your bust, waist, and hips and the tool gives you the right size in US, UK, EU, and AU — plus a note on whether to size up for fitted bodycon or down for A-line ease. Use the calculator below to get your exact fit in 30 seconds.

Frequently Asked Questions
Should I size by bust, waist, or hips for a dress?
Bust is primary for most dresses. For fitted bodycon and sheath cuts, factor hips too. For A-line and shift, bust dominates and waist matters less.
Do wedding and bridesmaid dresses follow the same sizing?
No — bridal sizing runs 1–2 sizes smaller than ready-to-wear. A US 8 ready-to-wear is typically a US 10–12 in bridal.
How do I size a maxi dress?
Match bust to the calculator's recommendation. Confirm length against your height — most maxi dresses are cut for 5'7"+. If you're petite, look for a petite line or expect to hem.
What if I'm between two dress sizes?
Size up for fitted styles, match for A-line and shift. Loose drape is easier to tailor than tight pulls.
