Jumpers are great in winter and all but central heating often leaves me wishing I hadn't put on so many thick layers in the morning (especially in the office). Enter the sleeveless wool tunic; the perfect compromise. I've been wearing this one from Zara over jeans or dark grey wool trousers (seen here), leaving it on its own or layering on top of roll neck jumpers when the temperature calls for it.
