I order a size XS in this. I wear a size small to medium in shirts depending how if I like my fits loose or tight. This size actually fit me perfect. It fits my overall shape on both length and width. The material is very soft, breathable and provides all day comfort. My favorite thing about this top is the pocket. There are lots of pockets in them. There are 2 bigger pockets, one on each side. One the left side there is a medium size pocket that is also a pocket that fits a pen, this is awesome because at times pens fall out of the pocket and this makes them stay in put. On the right side there is small pocket this is great of keeping smaller things in your pocket with out it getting lost in the bigger pockets. I recommend these for any one looking for a nice professional look in scrubs.I received this product free for exchange of an honest review.
