My daughter bought this sweater in xs in white and i tried it on. it was a little too tight but long enough to wear with leggings so i ordered the red in a s. it just covers my butt in the back - not nearly as long as my daughter's. i still love the sweater and will wear it with jeans but it is way too short to wear with leggings. i don't understand how there can be such a difference in the same sweater - a size larger and at least 4 inches shorter! if not for that, i would have rated it a 5.
