Lingerie fit
Find your bra size
Two measurements are all you need. Measure, enter them below, and we’ll suggest your size.
How to measure
- Underbust: wrap the tape snugly around your ribcage, directly under your bust. Keep it level and breathe out.
- Bust: measure around the fullest part of your bust, wearing a non-padded bra. Keep the tape level but not tight.
- Write both numbers down in the same unit (inches or centimetres).
Tip: measure in front of a mirror so you can check the tape stays level all the way round.

Signs you need a different size
The band rides up at the back
Try a smaller band (and a sister size to keep the cup).
The cups gap or wrinkle
Try one cup smaller in the same band (e.g. 34C → 34B). If the band also feels loose, go down a band as well.
Spilling over the top or sides of the cups
Try a larger cup.
Straps dig into your shoulders
The band is probably too loose, so it isn’t doing the lifting. Try a smaller band.
Fit varies by brand and style. We’re happy to help you try sizes in store.
