Julia Sarr-Jamois is making waves for Spring 2012. First, she starred in Tibi’s campaign for the season and now she is one of the faces of Barneys New York’s “Tree Time” campaign. Shot by famed photographer Mario Sorrenti and styled by Melanie Ward, Julia wears a slew of high-fashion looks from The Row, Marni, Giambattista Valli and Balenciaga.

She also dishes on her style in a video for the campaign.

Other stars of the campaign include blogger Jane Aldridge of Sea of Shoes, model/rock singer Sybil Buck, graphic designer/fashion art director Sofia Sanchez Barrenechea and model/musician Sarah Ruba, among others.
