Great cotton t-shirts for girls and boys
Special Size: T Shirt, Size: 4-5T, Color: T Shirt - Toddler - 6 Pack - White
These say they are for boys. Really, they are just plain t-shirts. Bought and tie dyed for an adorable little girl in my life. Very soft, and the cotton absorbed the dye well. Recommended for all girls and boys.

Good
Number of Items: 3, Color: Grey/Blue/Sea, Size: Medium
Really good quality for everyday wear. The fabric is soft and comfortable, and the shirts are true to size. They hold up well after washing and don’t shrink. Perfect basic tees for kids — easy to mix and match and great value for the price.

Size up, great quality
Number of Items: 3, Color: Grey/Blue/Sea, Size: X-Small
I ordered the XS and I have to say they run small. They fit my 2 year old not 6 year old. So size up. But honestly love the quality of Amazon essential shirts. I buy these for my kids pjs they are very soft
