I'm not particularly overweight-a cuddly size 12 (9 1/2 stone and 5 foot 3), and a 34DD, but I have horrible armpit chubby bits which I think look crap in vest tops.
Is this something you either have/not have and need to dress accordingly-ie thicker strapped vest tops?
Or is it due to a badly fitting bra?
Can you do excercises to get rid of it?
If I lost weight, would it vanish!?
