It's time to swap the cardi for a much more tailored alternative - the tuxedo blazer. It's a stylish option to throw over a shirt, blouse, vest or waistcoat and keep the chill off. It's also versatile - wear it to the office then bling it up with some killer earrings, a pendant or even a neck scarf to add some evening glitz.

Where to buy: Kate Moss for Topshop, £80 and Lux Lili tuxedo bomber from Urban Oufitters, $68.
