This weekend, women (and men) marched for equality around the world. Many celebrities participated, including Blake Lively, who joined her Sisterhood of the Traveling Pants costars and real-life BFFs America Ferrera and Amber Tamblyn.
Now, Lively is reflecting on the experience and explaining to fans exactly why she turned out in person to support the cause.
"I marched for my daughters, for my friends, for strangers, for myself, for Phoebe here in this picture who I met as she motivated everyone she came across," she wrote in a moving Instagram post. "My march wasn't driven by hate. It was rooted in a very simple fact—we are all equal."
She continued, "I believe everyone can agree on that. Thank you to everyone who marched all over the world. I felt so hopeful and deeply grateful. #whyimarch"
Yep, that sums it up perfectly. 🙌
