Fabric of Dress Shirts & Sport Shirts
Dress shirts are typically made from cottons of finer weaves like twill, broadcloth and pinpoint oxford. Often these shirts will have a slight sheen to them because of the tighter weave. This just adds to the dressiness.
Sport shirts are less formal (thus, traditionally made for ‘sport’), and can come in more rugged weaves like plain oxford or flannel, or lighter weaves such as linen and chambray. They also come in more colors and different patterns.
