Very compressive
Size: Large, Color: Pink
Super compressive for girls clothes. Great dress though, my daughter didn't love the feel of the super tight athletic wear feel though.

Size up 1
Size: Medium, Color: Pink
Great dress! It is your typical athletic material. The pink is pretty and matches the picture. Definitely size up 1! My child is a S and I sized up to M based on other reviews. It fits well and is a great length.

Runs Small
Size: Medium, Color: Pink
My daughter usually wears a 7-8. Size 8 pants have to have the elastic pulled tight. I got the size M (8 years). It was way too tight on her. Had to send it back. We did like the way it looked and felt, but just too small.
