Rooney Mara Goes Green In Louis Vuitton: Rooney Mara looked stunning in green, as she left the International Film Festival in Santa Barbara over the weekend. The actress wore a emerald structured by Louis Vuitton, with multi-strap heels and her hair in a ponytail smooth. Green is a major trend this season, with designers, including Roksanda Ilincic, Marc Jacobs and Proenza Schouler in the shade with their spring / summer collections. We even spotted green eye makeup Meadham Kirchhoff and green hair at Thakoon! Going green just got glam.
