During the event, celebrities and teen supporters packed up jeans that were donated to a local L.A. area homeless shelter along with letters, photos and videos with words of encouragement.

To kick off this year’s campaign, Aéropostale donated 1,000 brand new pairs of jeans to be packed up during the event in addition to the 10,000 brand new pairs of jeans that they are donating to youth shelters around the U.S.
