I've been wearing a 40E/42DD Did the booborbust calculator this morning, it said 38G as a start. (Measurements were 38.5 tight, 39.5 snug, 47 leaning, 46 standing). Went out and tried one on, it was comfy. No back fat, side boob, but, I forgot to not fasten in tightest hook. It fit fine in shop, but curled up on the sofa the cups are gaping and the gore is floating. I feel I need to scoop whenever I stand up. Obviously, it doesn't fit!
Where did I go wrong? Band too big? Cups too big? It's a balconette style because that worked before (boobs are pointy when unconstrained!)
