I am a bit confused about how to consider bra size for swimsuits. I take. 30ff bra size and have bikinis tops in that size which fit well. I normally take a 12 in bikini bottoms. Looking at 30ff swimsuits they seem to be a size 8, so to get one that fits my bottom do I need to get a 34 E size? Or something in between like a 32F? Or am I a weird shape and should forget it and just buy a size 12 swimsuit? I am looking at Freya if that helps.
