After watching John Samson’s infamous, trippy 1977 documentary, “Dress for Pleasure,” which profiles leather, rubber and vinyl fetishists, I don’t really have any better idea why some people gain sexual gratification from dressing in these materials. But it’s still a powerful movie that’s hard to look away from. It also gives a glimpse into Malcolm McLaren’s SEX clothing shop in London and serves as a pretty great fashion documentary of the type of punk wear that his partner Vivienne Westwood later brought to the mainstream. I would point out that several bare breasts make this film NSFW, but if you’re watching fetish documentaries at your desk, you obviously stopped caring long ago. (Thanks to The Documentarian.)
