Sentence:  The hideous holiday <WSD>jumper</WSD> became a big trend in the 1980s, influenced as we were by the TV-am gang, Gordon the Gopher and memories of Andy Williams singing to girls as they walked by on his Christmas specials. (Can't blame 'em, given he was wearing one of his knitted monstrosities.) 
Meaning of the word marked with <WSD> tags:  A woolen sweater or pullover.
