cotton blend
Color: Blush Pink, Size: X-Large Tall
The item says it is 55% cotton and 45% polyester. In fact the shirt label says 100% cotton. Very satisfied with the shirt as it looks good, wears good, and a nice shirt overall

Good quality
Color: Crisp White, Size: Medium
Fit is great, feels like a durable material. Generally a very nice shirt! Bought this for a 5’ 10” male who is 150lbs. Medium was just right, with a little bit of breathing room.
