Old Guard leather

The leather subculture denotes practices and styles of dress organized around sexual activities that involve leather garments, such as leather jackets, vests, boots, chaps, harnesses, or other items. Wearing leather garments is one way that participants in this culture self-consciously distinguish themselves from mainstream sexual cultures. Leather culture is most visible in gay communities and most often associated with gay men (enthusiasts are nicknamed "leathermen"), but it is also reflected in various ways in the gay, lesbian, bisexual, and straight worlds. Many people associate leather culture with BDSM (Bondage/Discipline, Dominance/Submission, Sado/Masochism, also called "SM" or "S&M") practices and its many subcultures. But for others, wearing black leather clothing is an erotic fashion that expresses heightened masculinity or the appropriation of sexual power; love of motorcycles, motorcycle clubs and independence; and/or engagement in sexual kink or leather fetishism.

Gay male leather culture has existed since the late 1940s, when it likely grew out of post-WWII biker culture. Early gay leather bars were subcultural versions of the motorcycle club with pioneering gay motorcycle clubs including the Satyrs, established in Los Angeles in 1954; Oedipus, also established in Los Angeles in 1958, and the New York Motorbike Club. Early San Francisco clubs included the Warlocks and the California Motor Club, while early clubs in Sydney included the South Pacific Motor Club (SPMC). Leather Clubs for gay men started in Amsterdam and Berlin in the 1950s, and in Sydney from 1970. The first gay leather bar, the Gold Coast, opened in Chicago in 1958.
