Let me start off by saying this bra is crazy comfortable. I've slept in it many times and that's something I never would've been able to do before. I originally ordered the size large (I'm a 36C) but found it all around too small; the band and the cups. The XL fits very well in regards to cups, but the band is far too big! It fits for maybe a day after I wash it, then stretches too far. I find myself having to wash it daily, which I fear will shorten the lifespan of this bra.
Overall love the bra, hate the fitting system
