Sif may be considered one of the guys in "Thor: The Dark World," but Jaimie Alexander showed off her womanly curves — and then some — at Monday's premiere.

The 29-year-old brunette wasn't going for a modest look at the red carpet event. Her daring dress, a creation from Azzaro Couture, featured black sheer panels, which left little to the imagination with both her front and backside largely exposed.

Needless to say, undergarments weren't part of the ensemble.

"It's surprising how dental floss can keep you warm," Alexander, who is dating "Twilight" actor Peter Facinelli, joked to Yahoo Movies on the red carpet.

Funny enough, Alexander told "omg! Insider" part of the reason she selected the dress — a decision made just days before the premiere — was because it "covers all my tattoos." The ink lover has several tats on her arms, the most recent of which she had done last month. While most of her body was exposed, the long black sleeves masked her body art perfectly.

"I wanted something old but edgy that still had some class. That's my personality," she added. "I'm a huge fan of Azzaro, so I'm absolutely pleased that I get to wear that designer."

While Alexander certainly has people talking about this dress, she's not the first star to show some serious skin while embracing the cutout dress trend. Perhaps most memorably, it was worn by Gwyneth Paltrow at the "Iron Man 3" premiere in April — and the GOOP founder has since gotten a lot of mileage out of it discussing it, including sharing her shaving habits.

Other stars giving rocking the cutout include Zoe Saldana over the weekend at the LACMA gala, Selena Gomez, and Jennifer Lopez, proving skin is in right now in Hollywood.

Consider yourself warned.
