It's comfortable as a sleep bra, but doesn't provide enough support for day wear. Also, the triangular structure of the bra is very open and doesn't keep the breasts in place. I sewed up my BDA bra under one breast and stitched it closed in the middle and that has made it much more supportive and comfortable. I made it work for me, but as it is I wouldn't recommend it (especially if you're on the XL/L side like me).
Wear mine almost every day, it fits perfectly
