Some Curves/Average Height
I am a small person- I am an XS in tops and I am quite slender, and the sleeves on this top were way too tight. I lift weights so I have muscle, but I'm definitely not bulky. So, I guess if you order an XS, you had better be a super model with ultra thin arms! The fit in the torso wasn't super flattering, either- it is too billowy in the front for my tastes.
