Purchased this and absolutely love it. You can seperate the pieces which is super nice, but they look great as a set. The fabric for the top is thin, but it feels soft and nice quality. The skirt waistband is nice and thick.
I got a medium. I am 5-3 and 120lbs. I really needed a small top but the medium skirt fits perfect so if you are bigger on the bottom fit to the skirt.
