's oversized bun was the perfect statement-making accessory for the 2012 Academy Awards. To duplicate her elegant and exaggerated 'do, begin with straight tresses, or slightly smooth out natural curls and waves. Then, make a center part and pull hair back tightly and secure in a ponytail two inches above the nape of the neck. Next, pull a hair donut around tresses and secure it at the base of the ponytail. Begin by taking small sections of the ponytail and wrapping them around the donut until all the hair is covering it. Insert u-shaped hair pins to keep the bun in place and mist with hairspray to complete the look.
