Olivia Wilde took it all off on HBO’s Vinyl this week, and she even wore a merkin–or pubic wig–as well.

PerezHilton.com reports that Olivia Wilde had to be historically accurate with her nudity. Vinyl takes place in the 1970s–long before women trimmed, shaved, or waxed away their pubic hair.

In a recent interview, Olivia Wilde talked about the merkin she wears on a regular basis.

“We all wear merkins because it’s the ’70s. They fit you, they make it, and they let you choose the consistency and the color. It’s huge…You’re wearing a little fur bikini…I was walking around to the whole crew going, “Look at this!”‘ she explained.

Wouldn’t you love to know what Olivia Wilde’s other half–funny man Jason Sudeikis–has to say about her pubic wig? That would make the perfect SNL skit if only Jason was still part of the Saturday Night Live cast.
