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..

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.
