There is nothing stronger, fiercer, or more beautiful than a close-knit group of girlfriends. Female friendship is a powerful force. Women are unstoppable on our own, but when there's a group of us, we can take over the world. I think every woman needs a group of female friends who complement them, support them, and uplift them. Your group can consist of two friends, or four, or eight – just make sure that your squad follows these commandments for female friendship.
