For the rest of us, wearing a jazzy jumper and donating £2 (all you need to do is sign up on savethechildren.org.uk before 10th December) is a great start, so long as you eschew the polyester fast-fashion offerings for something a little more… ahem, graceful. After all, there’s nothing wrong with buying something new and smile-inducing – a piece that is neither Christmas-specific nor too drab – so long as you plan to wear it often. That means no flashing lights or slogan Dad jokes; instead lots of fun, flattering colours in natural fibres and a style you’ll want to wear until spring. 

After all, a Christmas jumper should never be just for Christmas.
