International Women’s Day is a time to celebrate the countless achievements of women. Women around the world — and even a few of our go-to brands — have been celebrating in various ways, whether it’s marching, posting to social media, donating sales proceeds, or simply showing their support with their fashion choices. Of course, a selection of outspoken celebs took to Instagram to show their sartorial support.

1. Emma Watson: The Beauty and the Beast actress is celebrating by curating National Geographic‘s Instagram feed, sharing photos taken by female photographers all over the world — and sporting a red satin blazer featuring the words, “Girls just wanna have fundamental human rights.”

2. Lucy Hale: The Pretty Little Liars alum wore the “Phenomenal Woman” tee. The famous quote is taken from Maya Angelou’s iconic poem reading, “I’m a woman, phenomenally. Phenomenal woman, that’s me.” You can snag it for yourself from for $35. Hale said, “Over the last year, we’ve seen an unprecedented movement for women’s rights, and one thing is clear — our time is now. We are phenomenal, and we will make the world a better place for all women.”

3. Hilary Duff: Duff’s new glasses for Glasses USA will have $5 of their proceeds donated to FREE THE GIRLS, an organization that helps “reintegrate female sex-trafficking victims into their communities.”

4. Ashley Graham: The model wore black in her International Women’s Day post, like the attendees for the Golden Globes. She posed with her fellow Revlon Live Boldly spokesmodels in a campaign which “seeks to inspire women to express themselves with passion, optimism, strength, and style.” “On #InternationalWomensDay, I’m excited to be part of this bold group of amazing #LiveBoldly women!” the trendsetter explained.

5. Reese Witherspoon: Witherspoon’s lippie makes a major statement. She explained in a Facebook video that she’s been working on a limited-edition lipstick with Elizabeth Arden with proceeds going to the United Nations Women’s Fund. According to Witherspoon, Arden is the “creator of wearing red lipstick as an act of feminism.”

6. Julianne Hough: The Dancing With the Stars judge also wore the Maya Angelou tee as she echoed a similar sentiment to Hale and added, “We are PHENOMENAL, we are POWERFUL in our own unique and feminine ways, and we will make the world a better place for all women!”
