I commute in really cheap (£5 - £7) jogging trousers from Chavs/Sports Direct, just choose the ones without the elasticated ankles. Worn over a set of cycling shorts for a long ride. They stretch well, dry fast, and are reasonably warm. Also OK off the bike if I stop off for a bit of shopping on the way home.
This sort of thing;

On top I'm a bit more fussy, merino next to the skin, breathable midlayer if needed and windproof or waterproof on top.
