The 23-year-old daughter of Reese Witherspoon took an edgy approach to her look with a head of bright orange hair that stood out in photos at Thursday's Celine Fashion Show at The Wiltern in Los Angeles.

She wore a seersucker striped skirt set trimmed in white with gold buttons, wearing the shirt unbuttoned to reveal a black string bikini top underneath. Phillippe accessorized the look with a light yellow Celine handbag and a pair of black strappy heels.
