Retailer H&M is presenting a new line of T's designed by celebrities to raise awareness and funds for HIV/AIDS relief.  Rihanna, the Scissor Sisters, and Timbaland are just a few of the stars who have donated their time and skills to create a line of hoodies, tanks and T's with 25% of the proceeds going to benefit AIDS relief organizations.

I tend to get a little squirelly about these T-shirt campaigns.  It just seems more logical to make a direct donation to an organization rather.  If you need a t-shirt anyway, though, best to make it one that gives back.  The line will debut in H&M stores in February.  (source)
