They are fluffy and warm and come in pretty much any colour combination possible.
Invest in a good jumper and it will last you for many winters to come, wear it on its own in autumn then with a coat on top when the winter ice and snow sets in. Neutral colours will go with most things but the current vintage obsession has seen a rise in Fair Isle and other retro funky chunky jumpers. Here are a few from the new autumn collections
Brown Dogtooth Print Jumper
Chunky Garter Stitch Jumper
Black Moustache Jumper
There are many different shapes, colours and patterns to choose from but personally I go for the brightest and most unusual, the type that no one else dares to wear! But choose one that you like then it can never go out of fashion.
