I wear an xs in The Limited tops, and ordered an xs in this shirt. The fit is perfect. I decided to hand wash this in cold water and lay flat to dry to make sure it didn't shrink, which worked. The side rouching makes for a flattering fit. If you like to roll your sleeves up a lot, they are a little tight... and they roll up comfortably to 3/4 sleeves on me. I haven't come across the seems ripping or tearing like I read in another review. My guess would be size up, it is a fitted shirt. I've dressed this shirt up for work and also paired it with skinny jeans and a sweater. I love it and considered buying it also in the black and white.
