Most popular hairstyle this year: long side braided hairstyles. Rachel Bilson plays it charming and casually trendy with this fun side braid.

The hair is given a few additions of highlights and low lights, to break up and balance an otherwise dark brown shade of color. The hair is given a deep part in the center and comb down behind the ears. The hair is then pulled back to one side into a loose ponytail and tied with a brown hair tie. The ponytail is braided and tied approximately 5 inches from the ends of the hair. A few locks of hair in the bangs have been pulled out and given a gentle curl with a curling iron to frame her face.
