I've done the measurements and it came up 32 F, I almost collapsed in hysterics! I am no way that size, you can almost push my boobs together and cup them in one hand! Even my partner said no offence but that is wayy off. Upon putting the measurements into other sites it says 36 C, sounds more plausible. So I went and got some of those sizes. But they don't fit either! When I lift my arms up my boobs pop out of the bottom! The back where the clasp is, rides up so not sitting straight. I'm so annoyed! But I still don't think Boob or bust is correct?
