What naff Christmas jumper?

Do you remember the time when Christmas jumpers were naff?  So naff that you wouldn't be seen dead in one?  I've been thinking about this recently - with Christmas Jumper Day at work and even National Christmas Jumper Day on Friday 12th December - when did Christmas jumpers become acceptable?  In Bridget Jones's Diary (2001) our queen bee laments Darcy's choice of jumper (green with a large, gaudy reindeer on the front) whereas now, in my humble opinion, gaudier really is better when it comes to winter wear.  Be it polar bears, pompom snow, penguins with stripy scarves or full on Santa-style stuffed red belly jumpers, there is a jumper for everyone and it is now deemed almost unacceptable not to wear one in the Christmas season!  Do you have a favourite Christmas jumper?  In case you were wondering, mine is bright red with white ski chalets and sequinned stars on the top.  Classy, I'd say.
