The wide band at the bottom rolls up and retains sweat, creating a wet, uncomfortable, chafing mess. The kind that leads to a nice red rash. This roll of bra band makes an unsightly bulge in your clothes.

I can't believe I got the same bra the other reviewers did. Maybe they never left the couch. I'm not overly active either. I achieved totally misery walking a small dog very slowly just a few blocks in March. I swear my pulse never went up. I wear a 40C and its totally unsuitable for sleeping in also for the same reason. The band at the bottom rolls up and retains sweat there. The rolled up wad of bra is uncomfortable to lay on even when its dry. Even if you don't sweat while sleeping, you don't need a roll of bra fabric stuck to your rib cage.

Oddly enough, if they had put an actual bra band on it, it would work. Why they decided to be cheap and leave that off is beyond me. Bali is my favorite bra company.

This might be OK for the extremely thin. Why it comes in my size is beyond me because its a total engineering failure. I wish I could give it no stars at all. Actually, I wish I could un-order it.
