The Soma Size Chart, Interactive

Soma's chart covers A to H on 32 to 44 with comfort-first construction: stretchier top cups and softer wires than the department-store norm, which its runs-notes below reflect.

Reading it

How Soma sizing reads

Soma’s chart reads band-then-cup in inches and US letters: the alphabet doubles after D (DD, DDD) before jumping to G. Your measured US size maps straight onto this chart with no letter translation.
