The mostly-male participants met at the corner of Market and Castro where Muni’s F-line turns onto Market Street, without a stitch of clothing.

The so-called Nude-In was organized by Mitch Hightower who said it’s all about body acceptance.

KCBS’ Mark Seelig Reports:

“Everyone deserves to feel comfortable in their own skin,” Hightower said, adding that it’s a preview for Sunday’s Folsom Street Fair, renowned leather and fetish event.

It also happens to come around the same time that San Francisco Supervisor Scott Weiner introduced some new nudity guidelines that requires nudists to cover up their seat with a towel when sitting in a public area.

One man named Will from Santa Rosa came to participate.

“I’m an art model. I get naked for a living. I’m in my work uniform,” he said.

Dozens more like him were seen standing, sitting or simply having coffee, but of course in the nude. They got a lot of looks from those passing by.

“It’s their right. As long as it’s not illegal,” said one eyewitness.

Hightower said as far as he knows it’s not illegal and that if all goes well, they’ll try to make this an annual event.
