The burlesque queen Dita Von Teese is the latest celebrity ambassador to join Katy Perry, Róisín Murphy, Pharrell Williams/N.E.R.D., Estelle, Yoko Ono, Cyndi Lauper, Tokio Hotel, Yelle, Robyn, Dangerous Muse and Katharine Hamnett in H&M’s “Fashion Against AIDS” and “Designers Against AIDS” charity campaigns. Each musician has collaborated with the brand and designed a piece of clothing with a personal safe-sex slogan printed on it. I totally support the concept and the message.
