Dying of a cold and bad back, so apologies for the slightly waxy ill face.
I have discovered (somewhat later than most) that corduroy trousers are much warmer than plain cotton ones. This is obviously pretty straight forward stuff, but then again I am sure you're not reading this expecting fabulous fashion scoops (if you are I apologise, but you're in the wrong place). I usually have a bit of an aversion to the fabric on the account of cord not being as flattering as denim and associated with a certain class and type of gentleman. If you live in the UK you'll know what I'm talking about, if you don't sorry I googled but can't find any pics to illustrate. Anyways, I took the plunge, bought a pair of £20 trews and lo and behold, they are warm buggers. I may be hooked.
