What does your ribcage measure?
I just measured mine because I think I've changed size, and it's 29. But one of my 34D bras feels very tight (but just right) on, albeit I think the cup size is too big now. I thought I was 32 now, but online guides say 30, surely this cannot be right when a 34 bra feels OK?
I can't go for measurement under any circumstances so pls don't recommend that. Thanks for any information.
