The number one way to pull your hair out of your face this summer? A topknot. Peaches Geldof and Kate Hudson show off wispy weekend versions while Cara Delevingne and Rosamund Pike nail more polished versions of Erika Bearman's (aka Oscar PR Girl) signature bun. The style takes minutes to perfect, at most, and there are no rules. Use the above looks for inspiration, grab a handful of bobby pins, and twist up your locks!
