Celebrities for H&M's Fashion Against AIDS 2009 Collection

Singers Katey Perry and Robyn are among the celebrities who have participated in Fashion Against AIDS 2009, the second collaboration between H&M and Designers Against AIDS (DAA).

The new collection comes after the success of the first in 2008. The concept is pretty simple: celebrities design t-shirts and other fashion pieces, and 25% of the sales price will be donated to youth HIV/AIDS awareness projects.

Other participating celebrities include Dita Von Teese, Cyndi Lauper, Roisin Murphy, N.E.R.D., Estelle, Yoko Ono, Tokio Hotel, Yelle and Dangerous Muse.
