Sarah Jessica Parker's 'do is essentially a backcombed bun and it's a fantastic, effortless-looking style for any event. To try her look at home, begin by brushing hair back, keeping it smooth against the scalp and tightly securing tresses in a high ponytail. Next, backcomb the ponytail to create a lot of texture. Then loosely twist the hair, wind it around the base of the ponytail and insert bobby pins or u-shaped hair pins to keep the bun in place. Mist the completed look with lots of hairspray and you'll be all set for the red carpet, a night on the town or even just a quiet evening at home.
