Fantastic but runs small!
Size: Large, Color: Aqua Blue
Runs quite small. Daughter is 9 yrs, 4.5 ft, 60 lbs, ordered large, was almost too tight to get on her body.

Great fit and comfortable for gym class
Size: X-Large, Color: Bright Pink
My daughter wore this for her gym class and it fit her really well. She didn’t complain about it being tight or uncomfortable, and she loved the color. The material feels soft and lightweight, and it held up well after washing. I’d buy it again in another color.

A very adorable, exceptional quality sweatshirt for a inexpensive price, bought two
Size: Small, Color: Light Mauve
I bought two of these for my granddaughters as well as iron on stickers from Amazon to put their initials on the front of the shirt. The sweatshirts were some of the best quality I’ve ever seen from the stitching, to the thickness, softness. And not to mention the price.

Great hoodie
Size: Large, Color: Navy
Got this hoodie for my son and he’s been living in it ever since. It’s thick, warm, and fits really well. The color looks even better in person, and it’s held up after a few washes with no fading or shrinking. You can tell it’s good quality by the stitching and feel. Definitely worth it if you want something that’s both cozy and stylish.
