I got this dress in a petite xs. i'm 5'4" and 110lbs. it fit just right. i usually wear a regularl xs in most brands, but with retailer, i noticed i always have to go to the petittes. anyway, the dress is super cute. love the diagonal striping and the draping is not too poofy which is great. the material is very lightweight on the bottom - which is good for spring/summer.
