Would like to get a couple of nice pairs of trousers for the colder weather and for work, but I'm not very sure what to look for. After wearing jeans for work for years I am in a business casual job where jeans aren't really the done thing. I've been wearing lightweight slightly barrel/pleated/drapey trousers with bare ankles but not sure how to convert this to winter. I always prefer bare ankles or my narrow Chelsea boots. What trousers?
