I read the reviews and have been gentle with the zipper. Fits nicely and is holding up nicely so far. Skirt has a decent amount of weight to it, it's not light as a t-shirt. So it does swirl a tiny bit as you turn.

I got size Medium. I am 135 lbs 5'6" and a C cup. It fit nicely on the chest (the straps stayed where they are...didn't slide out around to the sides). I wore a support undershirt but this is very form flattering for those of us wth a little extra weight in the tummy after pregnancy that is all out of proportion to the rest of us... it fits nicely.
