By now, you're probably familiar with Mondo Guerra, the charismatic Project Runway season eight finalist. Mondo announced his HIV-positive status on the show and is using his newfound celebrity to gain awareness for AIDS research. So, he's designed two super-stylish, limited-edition tees ($50) for Piperlime that are available today — World AIDS Day. The designs infuse Mondo's bold style and energetic graphics, and for every tee sold, Piperlime will donate $20 to amfAR. There are only 300 of them, so what are you waiting for? Head over to Piperlime now to grab a tee and do your part.
