Don't Miss:

We could not be more excited about a film starring three of our favorite actresses: Kate Bosworth, Krysten Ritter, and InStyle contributor Rachel Bilson. But then they had to go and add in tremendous fashion too! It’s almost too much. Almost. We spoke to the movie’s stylist, Ilaria Urbinati, and this is what she had to say: “I wanted the wardrobe to be stylish but in a subtle way, and not take away from the story of these girls. Kate’s character has a really ’90s minimalist look, which is nice because that’s so big right now, and it really suited her—lots of white and pale green and beige. Calvin Klein Collection is basically dressing her for the whole movie and they do that aesthetic so beautifully.  With Krysten’s character we went in the other direction: lots of florals and girlie colors. She’s almost a little more grunge. And Rachel’s character is a little more farm girl so she wears lots of gingham…a little Brigitte Bardot meets Daisy Duke.” Click through the gallery to see some images from the set and find out exactly what the chic trio is wearing!

She’s Sunglass Hut’s style director, has a new TV show Ghost Angeles in the works, and now InStyle contributor Rachel Bilson can also add an uber stylish movie to her resume.  Co-staring Kate Bosworth and Krysten Ritter, BFF and Baby follows three roommates coping after one of them has a baby, as reported by JustJared.com.  It will be released next year.  But only we can reveal that the film’s costumes will be just as chic as the actresses’ off-set styles. The movie’s wardrobe designer, Ilaria Urbinati, told us exclusively that the stars’ closets will mix rising talents with established greats.  Expect labels like Rebecca Minkoff, 3.1 Phillip Lim, Calvin Klein and Proenza Schouler. Swoon!  Sounds a little like art imitating Rachel Bilson’s real life fashion sense to us!
