Understanding Bra Sizes
Band Size
The band size represents the measurement around your ribcage, just under your bust. It should feel snug but comfortable, providing most of the support.
Cup Size
The cup size is determined by the difference between your bust measurement and your band measurement. Each inch of difference represents one cup size.
Sister Sizing
Sister sizes are bra sizes with the same cup volume but different band lengths. For example, a 34C has the same cup volume as a 32D and a 36B.
Why Fit Matters
Wearing the correct bra size improves comfort, support, and posture. An estimated 80% of women wear the wrong bra size without realizing it.
