    They fit well and look super cute only thing is wish is if they had little grips to keep the shorts from ridding up.

    Way too short

    Love the quality of this dress. Bought it on sale for my teen who is average height and sadly it is VERY short on the bum, like you can see shorts showing. Should have been marked "kids size" because it fits like kids - would recommend for 10-12 year old. Bought size S for a 5'3" slim build tennis player.

    Unfortunately I am reading it is not eligible even for a size exchange - was going to try M.
