The t-shirt will feature on all 17 editions of the November issue of the magazine worldwide, and McCartney posted on Instagram 'I wanted to design a t-shirt that empowers women and encourages them to look inside and to love themselves and others. I also wanted to make a statement that speaks to the rippling effects of what’s happening around the world. It’s time to speak out, woman to woman'.
