Back on Jan. 21, the first day Trump was in office, women across the nation participated in a march protesting the president’s campaign promises on women’s rights. Because nothing was set in action just yet, women united in fear to demonstrate against the administration. Now the organizers behind the Women’s March on Washington are calling for “A Day Without a Woman” to be held on March 8, in honor of International Women’s Day. Women are encouraged to wear red in solidarity, not to engage in paid or unpaid work, and to avoid spending money. Check out which celebs will be observing the day.
