Understanding Bra Sizing
Bra sizing consists of two components: the band size (number) and cup size (letter). The band size is based on your underbust measurement, while the cup size is determined by the difference between your full bust and underbust measurements.
Band Size
- • Measured around ribcage
- • Should be snug but not tight
- • Provides 80% of support
- • Usually an even number
Cup Size
- • Based on bust-underbust difference
- • Increases with each inch difference
- • Same letter can vary by band size
- • Should contain all breast tissue
