Rihanna spent the day at trendy retailer H&M as she launched her Fashion Against AIDS charity line, featuring a collection of T-shirts, hoodies and tanks aimed at young adults fifteen through twenty-four.

The line hopes to raise awareness of the disease among teens with slogans like “Believe” and “Stop and Think.” Prices are expected to range from $12 to $34.

Twenty-five percent of the sales from the collection will go to HIV/AIDS-prevention projects worldwide.
