McCartney has designed two shirts to raise awareness for her environmental campaign, Meat Free Monday (MFM). The collections will be sold in selected London Gap stores. Vogue UK reports that the organic cotton shirts feature a superhero and Stella McCartney’s signature Intarsia leopard. “MFM is about us all taking control of the environment we live in for our kids and the generations to come. Whether you eat meat or not, you can be part of this decision to limit the meat industry destroying our planet’s resources.” Stella McCartney.
