Bra Size Calculator

Everyone deserves a bra that fits!

Wearing a bra that fits is much better for your breast health. Follow these easy steps to ensure you are shopping for your bra size:

Measurement number 1: Measure under your bust line.

Put on your best-fitting, unpadded, under wire bra. Measure underneath the bust line and make sure to measure tightly. Be sure the tape measure is straight across your back.

The general rule of thumb for all measuring is: less than ½”, round DOWN, more than a ½”, round UP. So if your measurement is 32 ¼”, call it 32.

Measurement number 2: Measure over the bust line

Measure over the biggest point of your bust line. This is a looser measurement. Make sure the tape measure is straight. 

Please Select - carefully selected plus size bras, lingerie and swimwear from leading suppliers such as Freya, Fantasie, Elomi and Fauve Our sizes start from a 28 to 48 back and a cup size C to K

This diagram helps to explain the difference with back sizes and the size of the cup.  As the back size increases the size of the cups change.  So a 30GG will have the same cup size as 32G, 34FF, 36F and 38E.
