I got these to sleep in. I wear a 38D in a bra. Based on reviews I got a 38C. The cup Is not super supportive which I expected from other reviews but works well for sleep. Also the band is not very tight which I also expected from other reviews. This is just what I wanted for sleep. It keeps me comfortable. I can wear around the house if I want but I don't wear for a regular bra. I need more support for day.
