Whether a topknot is simply a pre-emptive effort to stay cool this coming Australia Day, any IT-girl worth her Instagram likes knows the difference between a slapped-together bun, and street style worthy hairstyle, is in the details. Why not take your cue from three of the most-snapped supermodels by letting your shades act as a guide to your style? Taking a break from her California-girl waves, Gigi Hadid’s neatly coiled bun perfectly balanced out her angular, Le Specs sunglasses. Meanwhile her bestie, Kendall Jenner followed through on the rocker vibes of her aviators with an equally I’m-with-the-band, messy topknot. Finally, New York-native, Karlie Kloss put her own uptown girl spin on the ballerina bun by pairing it with some equally classic, black frames. Take your topknot game to new heights.
