Bust Size Calculator
Find Your SHAPE Bra Size
Two measurements in inches, and we translate them into your SHAPE letter. It is a guide, not a verdict: between two sizes on a seamless style, go up one, and if you are unsure, a woman on our fit team will confirm it privately on WhatsApp. You never have to buy.
1. Measure the BustWrap the tape around the fullest part of your bust, level and relaxed.
2. Measure the UnderbustWrap the tape snugly around your ribcage, just beneath your bust, where the band sits.
Inches
Fullest part, tape level and relaxed. We round to the nearest inch.
Snug on the ribcage, where the band sits.
We never save your measurements. Only your SHAPE letter, and only if you choose to shop.
Next: read the SHAPE size chart to see what your letter means, why we go up one between sizes, and how to measure at home. Not sure? Send both numbers to WhatsApp +880 1322 881062 and we will confirm your size, privately. Free, and you never have to buy.
The SHAPE size chart
Developed by our founder, Monoshita Ayruani, from thousands of fittings of Bangladeshi women. It is why it does not match an imported brand's chart, and is not meant to.
