Understanding Bra Sizes
A bra size consists of two components:
- Band Size: Number is the ribcage measurement under your bust.
- Cup Size: Letter is the difference between band and bust measurements.
Sizing varies by brand and style, so always try bras on—and remeasure if weight, pregnancy, or hormones change your body.

How to Measure Your Bra Size
