I love the idea I can wear almost any size.
I started way to big but have settled on a C,D,DD cup depending on the outfit and where I am going.
I have thunder thighs so I think I can get away with DD sometimes.
At least Amy in Las Vegas (Just U) said they work.
I am 5'11 1/2" ~170 lbs - 34-36C''s-DD's.
