Karlie is in top shape, working out in Nike's latest collection
Karlie Kloss is a very busy girl. Hot on the heels of her Tamara Mellon and Donna Karan campaigns is her new assignment with Nike for the sports label's Autumn Winter 2014 ad campaign, in which she looks to be in perfect form.
A fitbie herself, Karlie wears the Nike Pro Bra collection as she breezes through workouts in the images, shot by Vanina Sorrenti.
"I love different strengthening exercises and intense workouts," Karlie said. "I like to switch it up. I think that's the best way to really challenge your body and become stronger in every way."
