Having had two kids and now being middle-aged, my flesh is headed south!  This bra is perfect for sleeping in.  I have also worn it during the day in the hot summer.  Not bad for this purpose, but minimal support. I would not buy this for a regular day bra unless you are very small up top. For best support, buy a smaller size than you would expect to wear.  I wear a size small in this bra.  My regular bra size is 36C.
