Olivia Wilde in A.L.C. | Alternative Apparel + Shopbop Launch The Message Bag

Olivia Wilde kept her look pretty low key and casual on Monday night when she attended the the Alternative Apparel + Shopbop launch party for their “The Message” bag, which was held at Treehouse at David Burke Kitchen in New York City.

The 28-year-old actress wore a simple black tank top that she paired with a pretty brown A.L.C. batik printed “Linds” maxi skirt, from the Spring/Summer 2012 collection.

Sophia Bush recently wore this skirt to a premiere in Hollywood.

Olivia finished off her look with a naturally wavy hairstyle, gold earrings and a pair of tan elbamatt leather “Koomelia” platform sandals by Rupert Sanderson.

Alternative Apparel collaborated with Wilde’s project Campaign Happiness to design the vintage army canvas bag to help rebuild Haiti after a nightmare of an earthquake hit in 2010. Proceeds from the purchase through Shopbop and Alternative Apparel will benefit Academy for Peace and Justice, a secondary school in Port-au-Prince.
