They are starting to look a little like something you'd have to buy a can of Raid to rid your apartment of.

Mary-Kate Olsen and her twin sister, Ashley, known for their casual, layered, bohemian style, will wear red carpet-ready couture gowns in an ad campaign for Badgley Mischka.

"Ashley and Mary-Kate have grown up to become America's young style icons. They have an amazing sense of fashion and individuality that intrigued us," the design duo of Mark Badgley and James Mischka said Wednesday in a statement.

Once they were adorable, roly-poly two year olds starring alongside Bob Sagett, now, like the rest of young Hollywood, they're buying into the belief that dressing like schizophrenic bag ladies is making them attractive to the opposite sex. I suppose this only works if you happen to be a Johnny Depp clay creation who accidentally stumbles upon their underworld lair. Otherwise, you're holding seances to get them the heck out of your drapes.

Because, after all, when you see ads for high end merchandise, those ads need to be starring Molly Sims. Whos under the jump. And definitely not undead.
