So, where are you guys buying your bras from?

I usuallu just go to la senza. im a size 32d. but i just find that their bras are really uncomfortable because no matter how tight i make the band or the straps, i find that the cup part of the bra like kind of sticks out/ doesnt fit me properly??? and i just really HATE that feeling.

so, does anyone have bra reccomendations for bras where the cups wont "stick out"/ will actually fit to my shape?
