I'm looking for a pair of cosy 'lounge pants' for DH. Not tracksuit bottoms, but straight legged, warm, pj-bottom style trousers for slouching around at home in. Challenge is that he's tall and slim (32 waist, 34 leg) and in the past the ones I've bought him have always been flapping around his ankles. I can't seem to find any that are a) in the right price range (up to about £35) and are nice. Any ideas?
