Today (Feb. 28), Dior announced its partnership with Rihanna’s Harvard award-winning nonprofit organization, The Clara Lionel Foundation.

Founded by Rihanna in 2012, the non-profit is dedicated to funding and facilitating groundbreaking education, health and emergency response programs for impoverished communities globally. In support of Rihanna’s philanthropic efforts, Dior will be donating a percentage of proceeds from each “We Should All Be Feminists” t-shirt – made famous on their Spring 2017 runway and Riri’s Instagram – to the foundation.

The t-shirts will be available in all Dior retail boutiques worldwide and Dior.com until May 15, as well as Saks.com (including an exclusive black version) from March 14 to March 28.
