Style tip for 2014: wear the same thing your best friend wears. Granted, you might associate coordinated dressing with 4-year-old twins or Little League teammates, but with this you wanna go more The Warriors; think ill-tailored street toughs united (but no violence, thanks). Icona Pop’s stage look was perfect for this: They wore the same plate-metal shift dress in contrasting hues and looked like a really chic cheerleading squad, and it turns out they weren’t the only fest attendees with the same idea. The two ladies in contrasting black and chartreuse had the perfect idea (and the bright looks meant they could potentially find each other in the throngs if they got separated), while the woman in the super-cute striped shorts said she changed her outfit to match when her homie came over in the shirt. That’s the spirit!
