Seersucker is a thin, all-cotton fabric, commonly stripe, used to make clothing for spring and summer wear. The word came into English from Hindi, which originates from the Persian words "shir o shekar," meaning "milk and sugar", probably from the resemblance of its smooth and rough stripes to the smooth surface of milk and bumpy texture of sugar.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 improved heat dissipation and air circulation. It also means that ironing is not necessary. Seersucker was first used in the United States by the working class but was later adopted by the upper classes. The material was considered a mainstay of the summer wardrobe of Southern gentlemen, who favored the light fabric in the high heat and humidity of the American South.
