Obviously I want to be comfy, but I want to look a little bit stylist too ..... So I'm thinking down the lines of layering a vest top/tshirt with a hoody, and then harem/tapered trousers (elasticated waist is mandatory!) with hi top trainers?
Hopefully this will be OK to get me from the car park to the terminal building in the UK, be warm and comfy during the flight (I'm always cold on a plane) and then I can take the hoody off when I land?
Any other suggestions, or does this sound OK?
