I read the size chart from the back. I originally ordered 4T for my boys. Too small for my 6 year old. Perfect fit for my 4 year old. I bought a size up for my 6 year old. I love that it looks like a tank top and they don't have to wear a tank top underneath. The material is nice and thick, just like a normal t-shirt.
