I always thought I was a 36/38 A/B but after deciding to invest in some new decent bra's as mine are all too tight or curling over I thought I would measure myself before splashing out. Well what a can of worms it has opened! I've been given sizes online from 36E to 38B to 40F so I'm more confused than ever. I know mumsnet has their own way of figuring out bra sizes and this is where I got the 36E from but that just doesn't seem right to me as I'm size 16 so my under boob area is bigger but my boobs are pretty small, so I'm wondering if I've done it wrong. Please help!
