Girl power, then make it fashion! On Sunday, October 13, some of Hollywood’s most dynamic women stepped out onto the red carpet of Girl Up’s second annual #GirlHero Awards — and needless to say, they all looked like the stunning boss ladies they are.

According to Girl Up’s website, the #GirlHero Awards took place on International Day of the Girl in order to honor “elite, inspiring women and men, and young women activists to celebrate what happens when we stand together to advance gender equality.” If that doesn’t sound like a worthwhile cause, we don’t know what does!

Speaking of being honored, Cara Delevingne, Kate Hudson and Jameela Jamil were all presented with special awards.
