Essential Tees
Number of Items: 5, Color: Navy, Size: XX-Large
Nice quality for some basic, essential tees. The ratio cotton to spandex makes it very comfortable to wear. Great value.

Good shirts
100% cotton. Yay! And thicker than the normal 100% cotton shirts I have found. Made well. Could do with better designs and colors but overall am happy.

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
