Good quality for a good price. My teen is outgrowing his medium clothes and into larges so it fit slightly big which I expected but that just means he should be able to wear it to his fall dance as well. Nice material, not see through at all even after dancing all night and sweating. Exact color blue as pictured. Very happy over all.

Great shirt for the price.

Size: 4X-Large Big Tall, Color: Sky Blue

Shirt fit perfectly and was true to size. The material seems to be of a good quality for the price, and it is surprisingly light weight when worn. I use these as daily shirts, and have only used it once so far. Did well after washing and required little to no ironing out of the dryer. Very impressed with the item so far.

Perfect for my teenage son.

Size: Small, Color: Blue White Pinstripe

My son has worn this shirt many times to temple for bar mitzvah services. It’s soft doesn’t wrinkle easily and very comfortable for him to wear. He receives many compliments on it. This is a relatively thin shirt sizing was accurate. Fabric is what I would consider Nice quality. Color is spot on.
