The best bras ever! So comfortable, the best of both worlds with separation and cleavage. My only complaint is I wore a really tight white shirt with it when I went dancing, and after a while you could see a line where the insert was because they had migrated up my breasts a bit. This happens occasionally when I've been moving around a lot. It doesn't affect the comfort of the bra, so it's not a problem for me unless my shirt is too tight.
I'm 5'2, 135 lbs, I think I'm a 34 C right now but it's hard to tell after I've stopped breastfeeding. I ordered a medium and they are pretty snug but not uncomfortable. I imagine a large would also fit me.
