Review on Flannel Plaid Shirt for Girls and Women with Long Sleeves, Button Down Cotton Shirts in Sizes 3 Months to US 2XL by SANGTREE by David Amarelo

Shirt fits and looks great on my daughter. However, it is NOT cotton as stated in the description! The label I photographed says 100% polyester! The outside is soft like flannel, but the back of the fabric feels more slippery. My daughter is 7 years old (50% weight and height) and I bought her 5-6 years old because I prefer her fitter. Seller please update description to 100% polyester. Polyester is cheaper than cotton, which should be reflected in the price.
