These days, music festivals have turned into some of the best street fashion shows. Lollapalooza Music Festival in Chicago is one of our favorite events of the summer to steal new fashion and outfit inspiration. This past weekend Coco Rocha was spotted wearing a pair of HABITUAL Ultra High Rise Thalia Shorts in Abyss at the festival. She paired the shorts with one of her husband’s T-shirts, vintage boots and aviators to make the perfect laid-back music festival look. She topped the outfit off with one fancy mustache!
