"Project Runway" Designer Mondo Guerra Does T-Shirts for World AIDS Day

NEW YORK (CBS/AP) "Project Runway" fan favorite Mondo Guerra is lending his design skills to a cause close to his heart.

Guerra, who shared his story about being HIV positive on the fashion design reality show, is partnering with online retailer Piperlime to raise money for AIDS research.

He designed two limited-edition T-shirts to launch Wednesday, to coincide with World AIDS Day.

Guerra says he thinks he was compelled to share his story on "Project Runway" because "now I have the ability to bring attention to a cause."

"Things happen for a reason," he adds. "Now that this is my life now, it has brought some opportunities. I think it's inspired a lot of other people to be courageous and step forward."

For each shirt sold, $20 will be donated to amFAR, an organization that focuses on AIDS research.

One shirt shows a tree with a single heart hanging from a branch and the other features a colorful skull in the Day of the Dead theme that dominated Guerra's final collection on the TV show.

The Mexican tradition of Day of the Dead isn't about death at all, he says, it's about celebrating the memory of loved ones. "I think it's a smart choice to use this for this cause."

The T-shirts are for women, though Guerra notes, "They actually printed a male version in extra small just for me."
