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. Many participants associate leather culture with BDSM practices and its many subcultures. For some, 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.

Leather is a strong, flexible and durable material obtained from the tanning, or chemical treatment, of animal skins and hides to prevent decay. The most common leathers come from cattle, sheep, goats, equine animals, buffalo, pigs and hogs, and aquatic animals such as seals and alligators.
