I had a good look round the shops at the weekend and tried several on but none of them were up to the job! I am 5'9", 12/14 ish with a big fat tummy and monster boobs - 34GG. I want something very plain and elegant which will hold me in and control my assets! Tried on a few in M&S - total disaster, clearly aren't designed for the boob challenge. Please help me.
