For those who get hot and sweaty, a vest may be the perfect alternative to a Christmas jumper. This Monki Patterned Holiday Knit Vest (£25) is pretty in pink with a contrasting green trim that really makes a statement. Fairisle inspired, the print is certainly Christmassy, yet could be worn year-round, too. Wear the sweater vest over a shirt for a look that will take you from the office straight to a festive pub night.
