Sometimes fashion has more of a purpose than simply making us look great. H&M has teamed up with Designers Against AIDS to create a line of t-shirts in collaboration with several celebrities to raise AIDS awareness. Called Fashion Against Aids, the collection will make its debut in H&M stores beginning February 2008. The shirts will be made of 100% certified organic cotton, and each piece carries a tag that reads, “This might be the most important piece of clothing you’ve ever had your hands on.” All celebrity collaborators, including Rihanna, Timbaland, and Good Charlotte, are participating for free, and portions of each purchase will benefit various HIV/AIDS charities around the world. Head on over to H&M in February, and you can do some good while looking good.
