BLUF (Breeches and Leather Uniform Fanclub) is an international fraternal organization of gay men and MSM sharing a fetishistic interest in leather breeches and uniforms. The leather breeches are worn inside tall leather boots known as jackboots. BLUF is a part of a larger leather subculture and the sexual aesthetic is similar to the exaggerated masculinity seen in the work of Tom of Finland. Members share interest in leather fetishism, boot fetishism, and uniform fetishism. Some wear leather uniforms reminiscent of German World War II era uniforms, but without the Nazi regalia or embracing of NSDAP politics. The other common uniforms worn are those of American style police motorcycle patrol and German police.
