What's more badass than having the strength and skill to repeatedly best your opponent? Doing it all in kitten heels, that's what. In this amazing vintage video from 1947, a group gathers around to watch a woman in a self-defense class show off multiple ways to counter different attacks from a man. She disarms him, pins him, evades his blows, and most importantly, kicks him square in the nuts — multiple times. Watch her unwavering swagger as she puts her talents to good use, and take note of some of her best moves, because you never know when they could come in handy.
