Following recent bra fitting posts, what do you do when one is slightly bigger than the other? Do you buy a bra to fit the smaller one and slightly squash the larger one with the wire (is this bad?) or buy a larger one and have extra space on one side which looks dodgy under tops? Eek! This is extremely common so no laughing boys!
I think I'd buy the larger size and use an insert or one of those chicken fillet things for the smaller side. The other option doesn't sound very comfortable!
