Feel sorry for Fearne Cotton – the poor girl had to pose outside yesterday to promote this weekend's BAFTAs in open toe sandals without even a pair of tights to keep her warm. Ouch! Other celebrities braved the cold weather too showing how to wrap up and stay chic. Lily Allen donned her trusty Uggs with a very eye-catching white fur Prada hat to sledge on Primrose Hill. Trinny Woodall also wore a fur hat with a dark fur coat and knee high boots to meet friend Liz Hurley who wore a fur collared jacket. So, if you want to keep warm this week team your favourite knee high boots with the biggest fur hat you can find. See below for some winter hats.
