Katie Holmes made a guest appearance on The Tonight Show With Jay Leno last night.

The actress who’s known for a preppy look opted for a more laidback look.

She wore a pair of Isabel Marant red jeans from the Fall 2010 collection, which we would expect from the likes of Kate Moss or Erin Wasson.

The jeans are doing nothing for her, but I like that she’s trying something different.

A Madewell Montauk mesh pullover over a white vest and Prada heels completed her look.

The thing I like most about this look is her hair.

Katie was on Leno to talk about her new movie, “Don’t Be Afraid of the Dark” as well as her super-hot Vogue España cover in which we see her channeling her inner dominatrix.
