Savannah Guthrie and Allison Oppenheim bonded quickly over having young girls who were obsessed with all things princess. But it got them thinking, what exactly is a princess beyond the frilly dresses and fancy accessories? Is she a woman in a leadership role? Is she a woman who helps people? These questions started what is now their book, "Princesses Wear Pants," and they hope to inspire young girls to "Be a person of substance. Be a doer," as Guthrie says. And by the way, they love princesses, too! Sparkles, frill, makeup...or not, the point is young girls can make a difference and do good in the world. It's a message for young boys and girls.
