Bra Size by Underbust Measurement

The underbust sets the band. Pick your reading, then slide to your bust.

Underbustinches → band
24″ → 2825″ → 2826″ → 2827″ → 2828″ → 2829″ → 3030″ → 3031″ → 3232″ → 3233″ → 3434″ → 3435″ → 3636″ → 3637″ → 3838″ → 3839″ → 4040″ → 4041″ → 4242″ → 4243″ → 4444″ → 4445″ → 4646″ → 46

Odd readings round up to the even band; if that band feels loose, the sister size on the band below is the fix.
