The calculation
Worked example
US 34DDD maps to UK 34E in this chart. It is a label conversion, not a measurement-based fitting.
Assumptions and limits
Does not choose a bra from body measurements, infer European band size or guarantee fit across brands. Band must be an even US/UK label; other brands may use different cup lettering.
