THE haircut of the year has arrived. Yes, already. Vogue is calling it the Chop, others have named it the Karlie, after the model Karlie Kloss.

Ms. Kloss, already a fashion world veteran at age 20, cut off about seven inches of her dark hair late last year. Vogue declared it the “cut of the moment” in a four-page feature story in the January issue, saying “the season’s new hair is swingy, sexy — and refreshingly easy to wear.”

The cut was the brainchild of the hairstylist Garren Defazio. It rests just above the shoulders, with some layering in the front, and is topped off with bangs. It echoes the signature 1960s haircut of Jane Birkin.

“I love it,” Ms. Kloss told the Web site Fashionologie backstage at a fashion show soon after the new cut was unveiled. “I can’t stop touching it.” She added that having short hair “actually takes the focus off your hair and puts the focus on you. I’m starting to realize that it’s all about confidence.”
