I originally ordered a M. My sister gave me hers about 2 years ago because it was 2 big for her and it was a medium. The top on that one was too big almost like an XL. Fast forward this year, I've returned both a M and an L thinking I just needed a bigger size but the XL is the same. The pants are short, might as well be capris and the top no matter what size you get is like a bra. They cut the fabric down or something because prior to this year it was great. I would only get this on sale.
