Most of us take our underwear for granted, but throughout history our undies have revealed a lot about who we are (king or peasant), how we work (in fields or factories) or the shapes we value (manly calves or tiny waists).

The third book in Annick’s 50 Questions series tackles questions such as “What’s that smell?” (Medieval Europeans thought bathing made you sick) and “Did boxers arrive in the Nick of time?” (When blue jean model Nick Kamen stepped out of his denims to reveal his boxers, sales of the underwear soared.)

Underwear has played a role in ancient crusades, city sieges and even modern economic predictions. Obviously, it’s time to uncover the facts about everything from loincloths and T-shirts to bloomers and lingerie. Young readers will laugh their pants off at the accompanying cartoons and get the bare, but fascinating, facts about the history of our unmentionables.
