I thought that kingkongrevenge was joking, but apparently Hugo Boss AG was founded in 1923 and became the official supplier of uniforms to the SA and SS guards ( http://www.no1-in-beauty.com/Articles/hugo_boss.htm ). The founder died in 1948 and his company started making suits in 1953.

Why was this downmodded? The close relationship between the Nazis and many prominent artists is well-known. Leni Riefenstahl was one of the most influential modernist directors. Rudolf Laban is taught to acting and dance students today. Nazism was highly aestheticized, and to great effect; Hitler's rallies were choreographed and so on. No doubt this is partly why many artists, including some great artists, were attracted to the Nazis.
