I sleep in this bra. I have loved Olga bras for years. I highly recommend this particular style number. I'm ordering another one next payday. It has support, comfort, and the straps do not fall off. Like I said, I literally sleep in this bra. This is probably too much information but one of my breasts is larger than the other and I feel even with this bra because of the support. I think this bra is brilliantly engineered!!!
