To mark World AIDS Day 2011, popular French designer Isabel Marant has lent her artistic genius to Gap, designing an exclusive women’s t-shirt for Gap’s (PRODUCT)RED initiative. The pale grey tee features pretty splotches of paint in violet, grass green, tangerine, and sunny yellow. In a press release, Marant said: “This is one of those rare occasions when fashion can do something to help make the world a slightly better place.” The limited edition t-shirt retails for $24.95 and is available exclusively at Gap.com now. It will also be available in Gap stores beginning November 25 and running through November 28. Most importantly, 50% of the profits from the sale of these tees will go towards helping eliminate AIDS in Africa. What could be better on a Friday than this?
