Looking for a chic way to keep cool this summer? Slip on an embellished headband like Keira Knightley or Emma Stone. Knightley matched a red floral accessory to her dress, while Stone's ethereal gold band stood out against her tousled waves. The intricate accessories flatter cuts of all lengths, and are an easy way to add polish to up and down 'dos alike. Plus, they're perfect for keeping your strands out of your face as the temperatures rise. Thinner versions tend to slide around, so make sure your band fits snugly before securing your updo. A light mist of hairspray around the accessory gives the style extra staying power.
