This just in from the people at Teens For Jeans (a great charity if you have never heard of them). Prior to this, Ashley has also been involved in a similar cause called “Donate My Dress“.

“The campaign, spearheaded by NYC-based teen retailer Aéropostale and teen not-for-profit DoSomething.org, raises awareness about youth homelessness by inspiring teens across the US and Canada to collect gently-used jeans and donate them to homeless youth right in their own communities. Last year, the campaign collected over 200,000 pairs of jeans and this year teens are already gearing up to top that effort. Drop-offs are located at all Aéropostale stores from January 19th through February 14th, 2010.

“When I heard the statistics, it was hard to ignore,” explains Ashley Green. “Traveling the country for Twilight and New Moon has given me the opportunity to meet teens from a wide variety of economic backgrounds. I want to do everything I can to help young people take action about this important issue.”

“Teens for Jeans is special because it engages everyone; our customers, store associates and the community,” says Aéropostale Senior Vice President of Marketing, Scott Birnbaum. “A simple act like donating a pair of jeans can truly have a direct and meaningful impact on someone’s life.”

Starting Tuesday, January 19th until Sunday, February 14th, people are encouraged to bring in any brand of their gently worn jeans to any Aéropostale store in the U.S. and Canada. Aéropostale and DoSomething.org will make sure the jeans are donated to one of the 600 local youth shelters that have been selected as partners. As an extra incentive for those who donate, Aéropostale will give an additional 25% off a new pair of jeans, though no purchase is necessary. Donors will also have the chance to win signed jeans from Shia Lebeouf, Chris Pine, Penn Badgley, Dakota Fanning, Taylor Swift and many more of today’s young stars.

“We love that teens will be racing to the mall this January, and they won’t be going in empty-handed,” says DoSomething.org Chief Marketing Officer Aria Finger. “We are thrilled to be partnering with Aéropostale on the third annual Teens for Jeans and engaging hundreds of thousands of teens to take action across the US and Canada.”

In addition to getting customers involved in stores, Aéropostale and DoSomething.org are encouraging teenagers in their local high schools and colleges to coordinate Teens for Jeans school drives. Students who collect more than 500 pairs of jeans will receive a banner for their school, recognition on the DoSomething.org and Aéropostale websites and the chance to win a pizza party for their entire class.
