Sad but true, one in three people who are homeless in the United States are under the age of 18. Usually they cannot afford to buy clothing, and have to rely on donations. Often the donations are not always of the best quality, and so Do Something and Aeropostle have teamed up to encourage you to donate your old and loved jeans to shelters. The campaign is called Teens For Jeans, and a few celebrities are even getting in on it. In addition, when you drop off your jeans, you will receive a 25% coupon for a new pair of jeans at Aeropostle . Pretty sweet, huh?
