In the United Kingdom, Ireland and some fellow Commonwealth nations, knickers is a term for panties or similar women's undergarments: "Don't get your knickers in a twist" (i.e. "don't get all hot under the collar," or, in US usage "don't get your panties in a bunch." Australian usage "don't get your knickers in a knot"). George Cruikshank, whose illustrations are classic icons for Charles Dickens' works, also did the illustrations for Washington Irving's droll History of New York when it was published in London.
