When we saw the überelegant twisted hairstyle that came down the runway at Carolina Herrera this past Fashion Week, we immediately began scratching our heads to figure out how to replicate it, but Allison Williams beat us to the punch. Her center part with a twisted updo is an easy way to translate Herrera's oversize rolls.
Achieving this style is surprisingly simple. Mist your second-day hair down with some hair spray, like Victoria's Secret So Sexy Style Hold & Finish Hairspray ($14). Part your hair in the center and pin one section to the side. Starting at your ears, twist the free section down your head until you reach the nape of your neck, and secure the twist with bobby pins. Repeat on the second side. Pull the loose hair on either side together, twist into a bun, secure with bobby pins, and finish with a mist of hair spray. You'll look like you just stepped off the runway.
