I’m a 34H… but, since once upon a time everyone wore them, they must work for everyone (Mrs Fitz, Claire, Brianna).
My favorite pattern is one that was designed with my measurements. It’s the tightness under the boobs that holds the girls up. Email/message/whatever LBCC Historical (she’s on twitter, etsy) and ask her. She’s lovely.
(The ones in this pic are actually too high up under my armpits… and my shift is wonky)
