OLD GUARD

Leather and Lace, a woman's BDSM support and social group, was founded in Los Angeles in 1980. The women of Leather and Lace learned the "old guard" traditions from the men of Avatar.[22] Leather and Lace had a code of conduct and a uniform that could only be worn once a member earned the right. In New York, there was LSM. Only members of the club were allowed to know that LSM stood for Lesbian Sex Mafia.
