Rachel Bilson, Scarlett Johansson and Kristen Bell might have completely different looks, but one thing they all have in common is their stylist Nicole Chavez. For Sunday night’s Teen Choice Awards, Nicole tells PEOPLE, “I wanted a very casual, fun, young vibe — I was gravitating towards really soft palettes,” for all her clients. Rachel was Nicole’s first client four years ago when they met on the set of The O.C. and Bilson encouraged her to start styling. Rachel, who won for Teen Choice Movie Actress Action Adventure for her thriller Jumper, wore a blue one-shouldered Brian Reyes dress (someone that Rachel “loves working [with]”). Of her longtime client, Nicole says, “Rachel is very natural with fashion. She’s not afraid to wear something that is a little different or unexpected.” Kristen Bell “immediately gravitated” to her Jenni Kayne hot pink skirt and nude cami. Of the look, Nicole says, “The color combo’s great. It’s super modern, cute. Perfect for Teen Choice.” For Scarlett, it was a Matthew Williamson chiffon dress with a burst of colors on the beaded shoulders, but, says Nicole, “The real statement will be about the jewelry. It’s fun to layer things and be more bold.” All the pieces were from Scarlett’s friend jewelry designer Sonia Boyajian, who designed her engagement ring. Like Rachel, Nicole says Scarlett isn’t afraid of a fashion risk. We love all Nicole’s girls’ looks. Tell us: Who was your favorite– Rachel, Kristen or Scarlett?
