Beautiful shirts for a wonderful price
This is a really adorable set of long sleeve shirts, and a great value for the money. They’re very soft and the colors are beautiful.. I washed and dried them before my granddaughter wore them, and so far they did not appear to shrink very much..

Great for the price
Number of Items: 5, Color: Blue/Green/Pink/Purple/White Unicorn, Size: Medium
Perfect size and fit for my daughter. She wears these shirts ever other day. They are stylish and warm enough for the winter months.

Good but small
Number of Items: 5, Color: Blue/Green/Pink/Purple/White Unicorn, Size: X-Small
These shirts do run small I recommend you size up overall the material seems pretty good. Thickness is pretty good. Good length I recommend you size up because even though it’s a good material, they will shrink.

Good Cat Shirt - Odd Material
Number of Items: 1, Color: Lilac Cat, Size: 3T
This was purchased for my 3-year-old - we NEEDED a purple shirt with a cat. This worked for both.
It's an odd material - it says 100% cotton, but it's slippery and doesn't seem like it would breathe well. For a kid's shirt, the price is great. I would not buy a matching one for myself, but that's okay, I don't need a purple cat shirt.
The 3T fits more like a 2T, and she's growing out of it fast. I will be buying it again in a 4T and hoping the sizes are consistent. It was a huge hit for the kiddo.
