Bra Size Conversion Chart

Like any clothing, different lingerie brands produce bras and bottoms in different sizes, despite them being advertised as a certain size. Some are accurate according to measurements, others are a little more generous (or less generous).

This can be so confusing and means that people are increasingly ordering multiple sizes of bras to try and find the right fit. Unfortunately, this is having a negative impact on the environment, because brands often don't resell returns - they'll just ship them off to landfill, which is terrible for the environment.

So we've created this handy conversion guide so you can measure your bust using the Confident Tiger Measuring Tape and work out which size you are (as close to possible) to the brands we promote on our site.

If you're not sure which size you are, you can book a Zoom fitting with our fit by sight experts at Coco-Boo Lingerie.`

Please note: different styles by the same brand also differ between sizes and this conversion chart is not definitive. It exists as a guide to help you choose the right size, based on extensive research from multiple sources.
