Seersucker

Seersucker or railroad stripe is a thin, puckered, usually cotton fabric, commonly but not necessarily striped or chequered, used to make clothing for hot weather. The word originates from the Persian words شیر shîr and شکر shakar, literally meaning "milk and sugar", from the gritty texture ("sugar") on the otherwise smooth ("milk") cloth.^[1] Seersucker is woven in such a way that some threads bunch together, giving the fabric a wrinkled or puckered appearance. This effect is often achieved during weaving by warp threads for the puckered bands being fed at a greater rate than the warp threads of the smooth stripes. (These are often of different colors but do not need to be.) The unevenness causes the fabric to be mostly held away from the skin rather than being plastered on it when wet with sweat, facilitating heat dissipation and air circulation. It also means that ironing is not necessary.

Common items made from seersucker include suits, shorts, shirts, dresses, and robes. In the United States, it is often made in white and blue stripes; however, it is produced in a wide variety of colors, usually with narrow plain and puckered stripes in different colors.
