Bought the three pack for my girlfriend and she not only looks great in them but she loves how comfy they are! She loves the athletic like fit and quality of them. She is 5' 0" on the dot, bought her an xs originally but she said it was a bit to snug under her arms, the small was the perfect and most comfortable fit for her.
