I have always worn an underwire bra for the lift but after wearing all day I'm ready to rip them off and can't even imagine sleeping in one. Those Ahhh bra commericals sold me on trying a soft bra and after looking around here on Amazon I tried this one. Bought a nude in large and I'm a 38DD. Fits fine, no roll up around the bottom, a bit of lift, no nip show through except in very lite weight white cotton T and best of all I forget I'm wearing a bra.
