After reading the reviews online of how the sizes run extremely small, I was hesitant to purchase, but since the clothes were fairly inexpensive I decided to go ahead and order anyway. I am 5"2, 110lbs and decided to get a size medium in the tops. Once they arrived I probably could've been safe with the small, but medium fit okay too. I am usually a 4 in pants and got the 7, which fit fine. They are skinny jeans though so maybe those just typically run small. The quality seems better than I was expecting given the price, and the order came EXTREMELY quickly! I placed it on a Wednesday and it arrived at my door that Saturday. Overall I am satisfied and would likely order again if I saw something I really liked.
