Juicy Couture just released its first-ever fashion film—watch the Karlie Kloss-fronted short above!—and in honor of its Take No Prisoners attitude, they are doing something for good. Every time you Tweet the hashtag #GirlsKickAss and @juicycouture together, $1 goes to Step Up Women’s Network, a nonprofit organization that empowers underprivileged teen girls through mentorship and after-school programs. “Not only do we share the brand’s ideals of empowerment and confidence, but we also recognize the innovative spirit of the video and are thrilled to be a part of the brand’s first foray into film,” Step Up CEO Jenni Luke said in a statement. You have from now through September 30th to send out your Tweets and start raising money—it’s a little effort for a big payoff!
