1. To get Rooney Mara's hairstyle, brush all of your hair up into bun, and secure it with an elastic.
2. Run a flat iron over your bangs to get them extra straight. Apply a bit of shine serum to your fingers and rake them through your bangs to give them movement.
3. Slide on a fabric headband in a bright color to complete your look.
