Last year, more than 670 teens were killed accidentally during prom. But you can reduce that number this year just by making one promise. Students for Safe Prom (S4SP) will promote prom safety across the country, and you can help get the message out: Have an amazing time at prom and be safe at the same time. Here’s how — read the S4SP promise below and click on the link at the bottom to add your name. Just for adding your name, we’ll send you three stylish S4SP removable stickers (one for you, two to share with friends!) to spruce up your limo, locker, fridge, or wherever else will remind you to have fun, keep the promise, and spread the word about prom safety — the accessory that will never go out of style for prom night. Pass the promise along to all of your friends and let the celebration begin! Visit cosmogirl and sign the pledge today!
