The superhero fancy dress worn by January Jones in the forthcoming X-Men movie is more than a little skimpy, the actress has said.

She is playing Emma Frost in X-Men: First Class, which is a prequel to the first three films, and she told the Los Angeles Times that her outfit is not subtle.

"The costumes are insane. It's a lot of very body-conscious stuff. If you look at the comic book, she's barely dressed," Jones commented.

Fans had been wondering if the character was about to have an outfit overhaul after pictures emerged of the actress in a long coat, but it seems her clothing is set to be as barely-there as ever!

X-Men: First Class opens in June 2011, but has another month of shooting left.

Fans may wish to look out for X-Men fancy dress in the UK, as some of the movie is shooting over here.
