I am 5’8 and weight 125lbs and an extra small is good. I have a small chest and it fits fine in the chest . length wise it is on the floor , if I wear heels it will be a slight drag . it is loose in the part below the stomach . I will get that brought in bc I am wearing this as a bridesmaid dress. but other than that it’s cute . good material . not as flattering in the chest if you have a small chest btw but overall worth the $20
