Jaimie Alexander wore a very revealing dress to the "Thor:The Dark World" premiere in L.A. on Monday. The actress left little to the imagination with a see-through front and back to her dress.

Jaimie Alexander may be done up in warrior's gear as Lady Sif in "Thor: The Dark World," but she showed off most of what's underneath that costume Monday at the movie's Hollywood premiere.

Her daring, see-through dress, by Azzaro Couture, according to RCFA, revealed a strip of skin from neck to toe, front and back, through mesh panels — and word from the red carpet was that as she walked, it revealed a bit more than intended on the skimpy tush side. Clearly she was going commando top and bottom.

"Strategically, there is tape in places that tape has never been before!," the 29-year-old told "Access Hollywood."

If you say so, Jaimie — the outfit didn't leave a lot of room for the imagination, much less tape.

Alexander, 29, has been dating "Twilight" star Peter Facinelli, 39, E! News reported. And now we can all see how very lucky he is.

The movie, which stars Chris Hemsworth and Natalie Portman, hits theaters Friday.
