It’s that time of year again: The Princess Project annual dress drive kicks off next week to collect new and gently-worn prom dresses and accessories for Bay Area high school girls in need.

Every year, the Princess Project manages to be one of our favorite charitable examples of using fashion for a good cause. Founded in 2002, the San Francisco non-profit organization has given prom dresses and accessories to over 15,000 teenage girls who might not otherwise have been able to afford the stylish gear to make this quintessential high school experience complete.

It’s also an excellent way to unload party dresses, formal gowns and cocktail numbers that, let’s be real, you’ll never wear again (and for anyone who’s experienced the bridesmaid-dress-conflicts-with-my-body-type-but-I-love-my-friend-so-I’ll-wear-it conundrum, consider the chance to help someone have a great prom a silver lining to those horrible pics you keep having to untag on Facebook).

Want to get involved? You can donate a dress or accessories at one of many participating San Francisco drop-off locations starting on Feb. 7. Before you head over, make sure your donation is contemporary and relatively in style (purchased in 2005 or later), dry-cleaned and on a hanger and in good condition. You can also mail your donation to The Princess Project, c/o Team Worldwide, 405 Eccles Ave., South San Francisco, CA 94080.

Those interested in receiving dresses for this year’s prom can sign up to learn about dress giveaway days planned for this spring.
