31 inch bust in cm, and the sizes it fits

What suits a 31 inch bust

A bust this size is common for teenagers and for petite, slim frames. Light, non-padded coverage is usually all that is needed: a soft starter bra or a slip-on sports bra, rather than a moulded cup with nothing to fill it.

Measure the underbust as well before choosing a bra. On a small frame the band does almost all the work, and a band that is too loose rides up the back however well the cup sits.

How to measure at home

1. Measure your underbust. Wearing an unpadded bra or none at all, run the tape snugly around your ribcage, directly under your bust. Keep it level and breathe out normally.
2. Measure your bust. Run the tape around the fullest part of your bust. Keep it level and don't pull it tight — the tape should sit flat without compressing.
3. Find your size. Your underbust gives your band size. The difference between bust and underbust gives your cup. Enter both above and we'll do the maths.
