Feminist activists, journalists and authors, Gloria Steinem and Dorothy Pitman Hughes, have announced the release of a limited edition charity tee to help raise funds to support the Equal Rights Amendment (ERA), a proposed amendment to prohibit discrimination against women and girls.

Notable supporters including Gillian Anderson, Patricia Arquette, Lena Dunham, America Ferrera, Jane Fonda, Josh Gad, Chelsea Handler, Debra Messing, Bette Midler, Jennifer Morrison, Amy Schumer, Rainn Wilson and Robin Wright have all taken to social media to post 'fist-pumping' photos with the hashtag #equalrightsnow.
