Please read as there are size details, etc.! The pink t-shirt is size 130. The other 3 items are size 140. The brand is listed as Gap Kids, but only the white t-shirt with hearts is from that brand. The Minnie Mouse t-shirt is from UT. There are a few small black spots on the lower front. Therefore, I have marked it as having some scratches and stains. Please be aware of this. The navy blue t-shirt is made of 100% cotton for the main body, and the others are also 100% cotton, making them cool and comfortable to wear. They are recommended for the coming hot summer.
