Blue Jeans 1871
Before jeans most men wore what was called trousers and/or slacks. For centuries, trousers have remained the standard lower-body clothing item for males; but, by the late 20th century, trousers had become a popular clothing item for females as well. Trouser is a tailored garment with a waistband, buttoned loopholes, and a fly front. Jeans are an outer garment covering the body from the waist to the ankles, with a separate part for each leg. Without jeans today there is no telling what people would wear.
