off on a sun holiday in less than 2 weeks and I reeeeeeeeeeeeeeeally don't want to take my winter coat! I'll be travelling to the airport at about 6am and will be getting a bus to a train station and then a train to the airport so will need something that is reasonably warm and not bulky. I don't have anything suitable and would like things that can possibly be worn on the holiday in the evenings, any suggestions? and what the hell do I wear on my feet? socks and sandals?? 
please help, can go (high street £) shopping, am size 16 so can't just wear leggings and a cashmere jumper and would like to look reasonably pulled together.
