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.

Love the look
Worth the money, adorable, cute, easy to match, and just love them for our daughter! Great price for 5 shirts! We did get a small for our little one who is tall, 36lbs, 4t-5t they are a little big but gives her room to enjoy more and longer.
