Sophia Bush wants to give someone the shirt off her back — literally.

The One Tree Hill actress and activist is selling designer clothes from her personal closet via Closets for Causes' eBay auction to benefit Pencils of Promise.

"Pencils of Promise rocks my world because they believe every child should have access to quality education," Bush, 30, tells Us Weekly in a statement. "They create schools, programs and global communities around the common goal of education for all."

Proceeds from the auction, which kicks off July 16 at 10 a.m. PST, will aid Bush in building a school in Guatemala through Pencils of Promise's The Impossible Ones campaign.

"Everyone has an impossible challenge: a milestone to reach, a daunting task to accomplish, a fear to overcome," Melanie Stevenson, director of operations at Pencils of Promise, explains. "Ours is 100 schools in 2012. By dedicating her impossible challenge to Pencils of Promise, Sophia brings us one step closer. Together, we can achieve the Impossible and create possibility for thousands of children around the world."

Bush has personally pulled each designer item from her wardrobe; Louis Vuitton, Herve Leger, Marc Jacobs, Christian Louboutin and Alice + Olivia are just a few of the luxe labels up for grabs.

"We are excited to help Sophia reach her goal to build a school for the children of La Guadalupana, Guatemala via Pencils of Promise," Closets for Causes founder Talia Bella says. "There are such amazing pieces in the fashionista's closet, and knowing that the proceeds are benefiting such an amazing cause is a win-win for our online shoppers."
