St Mungo's Woolly Hat Day

Show your support for the homeless at one of the coldest times of the year by taking part in Woolly Hat Day. The annual fundraiser is run by London's largest homelessness charity, St Mungo's, who are urging folk to bid in their celebrity hat auction (including headgear from Sir Elton John, Joanna Lumley and Benedict Cumberbatch), hold hat parties in order to raise money, or simply donate direct via their website.
