Frequently Asked Questions

How do I convert bust size to cm?

To convert bust size from inches to cm, wrap the measuring tape around the fullest part of your bust and note the measurement in inches or cm. If you measure in inches, multiply your number by 2.54 to get the value in cm. Example: 36 inches × 2.54 = 91.44 cm.

How do I read a US to UK bra size chart?

US and UK band sizes are the same, but cup letters change after D. US DD = UK E, and US DDD/F = UK F. Using a US-to-UK bra size chart helps you match the right cup when switching brands or shopping online.

What is the correct way to take a bra size measurement at home?

Measure your band by wrapping the tape under your bust. Measure your bust at the fullest part. Subtract band from bust to find your cup size. This gives you the bra size in the format band + cup, such as 34C or 36D.
