The rule used to be: match your bobby pins to your hair. But for spring, the blonder the hair the darker the pins-at least, at Prada and Sonia Rykiel. Once fall hit, Odile Gilbert suggested a brighter contrast, using primary-colored pins on all shades of hair in the Cacharel show. More recently, both Hanneli Mustaparta, a chocolate brunette, and Emma Stone, currently a near-platinum blonde, rocked white bobby pins against long, ladylike styles.This has to be the easiest runway-to-real way idea in the history of hairstyling. Whether you're in a rush, looking for a dirty hair fix, or lacking the fine motor skills to give yourself Heidi braids, you can pull your hair into a deep side part and secure with a fun assortment of bobby pins in less time than it'll take to apply the shine spray you'll need to polish off the look.
