Great summer denim shirt, made in seersucker fabric by Mazzarelli. Seersucker or railroad stripe is a thin, puckered, all-cotton fabric, commonly striped or chequered, used to make clothing for spring and summer wear. Seersucker is woven in such a way that some threads bunch together, giving the fabric a wrinkled appearance in places. This feature causes the fabric to be mostly held away from the skin when worn, facilitating heat dissipation and air circulation, which gives cool comfort in the warmer days. A great plus with this particular fabric is that ironing is not necessary.
