Slim-fit pants or skinny jeans (when made of denim) are tight trousers that have a snug fit through the legs and end in a small leg opening that can be anywhere from 9" to 20" in circumference, depending on size.

Other names for this style include drainpipes, stovepipes, tight pants, cigarette pants, pencil pants, skinny pants, gas pipes, skinnies, and tight jeans.

In the early 1960s, drainpipes were worn by numerous rock bands and musicians, including The Beatles, The Rolling Stones and Bob Dylan. Fashion icon Audrey Hepburn also raised the popularity of drainpipe jeans. Slim fitting pants and jeans were worn not just by members of the teenage Mod or greaser subculture but also ordinary people. By 1962, Sears were selling tight jeans made from "stretch" denim that incorporated elastane. The trend lasted until the end of the 1960s when "hippie" culture gave rise to flared pants and bell bottom jeans.
