Rockers (also known as leather boys or ton-up boys) are members or followers of a biker subculture that originated in the United Kingdom during the late 1950s and was popular in the 1960s. It was mainly centred on motorcycles and rock 'n' roll music.

Rockers come more frequently from broken homes and families with financial difficulties. They display more aggression, criminality, intolerance and dislike of other groups and have a higher alcohol consumption. They advocate physical strength and violence.

It's a groundbreaking style, that strays further from a classic and minimal aesthetic by combining more risqué and daring pieces. Fashion powerhouses like Balmain have embraced rock chic by adding studs, sequins, and faux leather into some of their most famous pieces and collections.

Rockers generally favored 1950s rock and roll, mostly by artists like Elvis Presley, Eddie Cochran and Gene Vincent Mods listened to 1960s ska music, soul and R&B, as well as British bands such as The Who, The Yardbirds and The Kinks.
