So I'm currently losing weight (1.5st so far), going from a size 16/18 to a size 12/14 and my bra situation is not good. I measured last night and my back came in at 31.5in and then I did the whole leaning forward and measure - this came in at 44in 
I'm currently wearing a 38f, but I'm sure this is wrong. Does anyone know what I'm supposed to be wearing? I do know that my chest looks massive now and I've been having a lot of back pain, so I am hoping a new bra situation will help.
