I really like this blouse. it's hard to find a short sleeved button down that the sleeves don't stick out and look weird. this one does not have this problem. it is a bit sheer, but i don't mind wearing a cami with it. it is flowy... but not boxy/baggie. has a very nice, flattering drape. i'm 5'3", 110lbs., 32c, petite frame. the 00 regular fits great. i'm often a petite (especially in pants and long sleeved tops)... but went with the regular size here bc i wanted the longer length.
