Breeches and Leather Uniform Fanclub. An organisation formed in 1997 for men (predominantly, but not exclusively gay) who enjoy wearing breeches and/or leather uniforms, similar to the ones shown in the drawings of Tom of Finland. BLUF organises regular parties around the world, and provides a website where members can post profiles and exchange messages with others. The term is also used as a shorthand to describe a type of clothing, for example in dresscodes or descriptions of items on auction sites.
