Dressed for Success
It didn't take long for Gigi to learn one of the most important rules of the biz: fashion over function. The astute model didn't let the snow and 20 degree temperature prevent her from rocking bare legs with this Tory Burch ensemble as she heads to the designer's show.

They Have A-List Friends
Cali girl Gigi looked very New York in this black and studded look as she rubbed elbows with supermodel Coco Rocha backstage at the Diesel Black Gold fashion show.

Working the Runway
A versatile Gigi went from playtime to business time, modeling two very different looks: a teddybear print babydoll dress from Jeremy Scott (left) and a chic belted dress from Michael Kors (next slide).

Celebrating Their Individuality
At DKNY, Bella (left) served edgy in head-to-toe black while Gigi (next slide) was photographed around Lincoln Center two days earlier in all white. "We have such different looks that we’ll never compete for the same job," Bella told Style.com, "...we are separate people with different looks.”

Making an Impression
Photos of Gigi in this football-inspired dress from the Tommy Hilfiger Women's Collection were quite possibly among the most circulated pics from Fashion Week. Sure, the look is fashion forward, but like the Hadid girls, it's definitely memorable.

Front Row Fashionistas
At NYFW, the front row seems to be photographed as much as the runway. When she wasn't walking in a show, Gigi was seated front and center among fashion's elite. During the Diesel show, she was seated with Coco Rocha, European models Toni Garrn and Amber Le Bon and singer Lizzy Plapinger.
