Underwear: What We Wear Under There by Ruth Freeman Swain

Fun picture book dedicated to UNDERWEAR!  I learned that astronauts wear diapers, hooped petticoats could be 6 feet wide and that in the middle ages men's leggings couldn't stretch and that's probably why in paintings, the men are pictured standing up.  Very interesting book.  And in the future, there might be underwear with ceramic particles to keep you feeling cool.
