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.

Adorable but runs small
Size: Medium, Color: Black/Ivory, Size: Medium, Color: Black/Ivory
These are the cutest shirts- cotton, soft, thick- good quality but SMALL. Returned because of size and ordered a bigger size. I added a picture for reference- the other is a cotton 7-8 from Disney - I feel like the M /8 amazon was more a 6. I definitely recommend these shirts though just size up at least one size.

Gift for granddaughter
Size: Large, Color: Mauve/Butterflies
My granddaughter likes these tops. They are sturdy, comfortable and soft. She loves the ruffles on the shoulder. They were reasonably priced and I feel they will last. Look good after a number of washes.
