If you've ever lusted over Emma Watson's feminine dresses or Olivia Palermo's chic separates, this is your chance to make them your own. The style stars along with other A-listers like Lupita Nyong'o, Diane Kruger, and Lena Dunham have donated pieces from their closets to Vestiaire Collective. The online shopping destination has partnered with Women for Women International to launch the Wardrobes for Women initiative. One-hundred percent of the proceeds from the sale are donated to the organization, so know that your shopping is for a great cause. Scroll to see a few of our favorites, and head to Vestiaire's site to shop the looks starting Dec. 3.
