Sophia Bush to auction off her designer clothes

Sophia Bush is stepping up her efforts to raise money for an educational charity by auctioning off her designer clothes.

The One Tree Hill star has cleared her closet and will put up a selection of brand new and lightly used pieces on auction website eBay.com to raise money for Pencils of Promise.

Louis Vuitton, Herve Leger, Marc Jacobs and Christian Louboutin are a few of the high-end labels Bush is offering from her wardrobe.

In a statement, she writes, "Pencils of Promise rocks my world because they believe every child should have access to quality education. They create schools, programs and global communities around the common goal of education for all."

Proceeds from the sale, scheduled to kick off on 16 July (12), will be put towards building a new school in Guatemala.

For her 30th birthday earlier this month (08Jul12), Bush asked fans to make donations to Pencils of Promise in lieu of gifts.
