Odette Yustman, Spencer Grammer, Rumer Willis as The Women of Woodstock:

“They were showing the world that being a little bit different is OK.”—Odette Yustman, 23, of the upcoming film Rogue’s Gallery
“These women didn’t have to look a certain way. They didn’t have to have a man. They could love whomever they wanted—that has definitely influenced who we are now.”—Spencer Grammer, 25, of ABC Family’s Greek
“It’s an era that was so important because it was very much about natural beauty.”—Rumer Willis, 20, of the upcoming horror film Sorority Row
