I am in the process of losing weight lost 2 stone so far 1 left to go until I am in the middle of the healthy weight bar on NHS bmi calculator. My current 34F bra has got to big in the cup now, there is a gap at the top and the fabric folds. Just measured again and it has gone down to a 32e, what is the sister size for this? I think 34dd, I have googled and not found the answer. I want to get the £8 bras from Asda as I'm still losing weight and only been this size for 4 months so don't want to spend loads until I am stable. The wash well and are comfy and have lots of colours to choose from, only problem is the 32 back stops at a d where the 34 back onwards go up to a g cup. The back of my current 34 band bra is on the tightest setting but doesn't move or ride up my back like my old 38 & 36 band bras did as I lost weight.
