Trousers (pants in North America and Australia) are an item of clothing worn from the waist to the ankles, covering both legs separately (rather than with cloth extending across both legs as in robes, skirts, and dresses). In the UK the word "pants" generally means underwear and not trousers.[1]
From http://en.wikipedia.org/wiki/Trousers - funny what you can learn :)
While scouting FB, I saw that 'Queen Rare photos articles and videos' page posted a scan of this. They kindly uploaded a larger resolution copy at my request. So a thanks goes out to this page :-)
