I intervened and got a 34gg, so far so comfy apart from it really isn't! I got a Freya moulded cup (I think a deco) from Debenhams and although I felt it nicely in the shop, in regular wear it is terrible :(
The cup gapes at the top of each boob by an inch at least all over, the sides dig right into my armpit bone/ cartilage and the cup comes right into my armpit. The band fits nicely and doesn't slip but it just feels like the cup is at least 3-4 sizes too big!!
Is it the design of the bra or just my odd Boobs? Please help because it hurts like buggery now :( and I can't afford to blow £32 on another bra to find the same thing happens!
