It's not just Amy Pond who knows how to dress to impress - her real life alter ego Karen Gillan has sported her fair share of seasonal sweaters, too. She and Matt Smith appeared in BBC One's Christmas ad back in 2011 for which they both got into the spirit by donning festive jumpers. If you want a piece of action, you can get your hands on Karen's jumper (known as 'Crazy Grandma', make of that what you will...) on Amazon while Matt's 'Reggie Reindeer' number is available here. If a Cybermen can find it in his emotionless heart to let go at Christmas, you've really got no excuse.
