I bought this to wear on New Years eve. I got the XS because I read a review that it runs big, and I'm really glad I got XS. Normally I worry that jumpers will be too short and show too much of my upper thigh, but this is not the case, it's really cute. I also tried on the Small, and while the length was fine, the overall fit of the top was way too big. For reference I am 5" 3", 117 lbs, and 34D bra. Excited to wear this with some heels on New Years Eve.
