I had my bra size professionally measured, yet it still feels like it doesn't fit. I'll admit, the twins are a little saggy and I'm a 34DD, but everytime I sit down, my bra cups pucker and it have to go to the bathroom and pull them back up. Am I wearing the wrong size or am I just saggy? Another think I think it could be is that I have a lot of stomach fat and the underwire sits on top of the fat and kinda lifts it away from my boobs.
