In Hollywood, female superheroes, goddesses, and warriors often have one thing in common: They all wear “boob armor.” It’s a breastplate with…actual boob cups built in. Wonder Woman and Xena Warrior Princess are prime examples of heroes with feminized breastplates. But like both of these characters, boob armor is fantasy. There are just two examples of female armor in the historical record, and they are only referred to in text, so we don’t know what they looked like. But it is highly unlikely the armor included breast cups, not least because it can literally kill its wearer. Watch the video above to find out why.
