The 3/4 inches thing has never worked on me. But I read somewhere that it goes out of the window once you get in to larger back sizes. That link would make me a G cup but I'm sitting quite happily in DD...![]()
Without looking at a pic I can't diagnose whether your bra fits. Is the back strap level all the way round? Do you have the straps relatively tight (the little moveable buckle thing near the top of your shoulder)? Are your boobs fully in the cup with no over spillage or wrinkled cups?
