Though it could easily be a wig, Hadid's ringlet curls were definitely a new look for her -- and she was clearly feelin' it! The popular young star totally owned the look and appeared confident and sexy with her new 'do.

Hadid's incredibly fit physique in the photo is surely enviable, but we also have our eyes on her retro Coca-Cola iPhone case.

"Still goin," she captioned the snap, alluding to the fact that she's still working incredibly hard despite the fact that she's coming off over a month of fashion shows all around the world. Hadid walked in shows in New York, London, Milan and Paris in each city's respective fashion week and, though she must be exhausted, she clearly hasn't missed a beat.
