What is Wear A Hat Day?
Wear A Hat Day is one of the UK’s biggest and best-loved brain tumour awareness and fundraising days, bringing people together across the nation as they put on their favourite hats and make a donation, or attend a fundraising hat-themed event.
Since its launch in 2010, Wear A Hat Day has raised more than £2.2 million to support our vision to find a cure for all types of brain tumours.
Brain Tumour Research has become synonymous with hats and hatting. A bespoke pink silk top hat created for us by Lock & Co. – the world’s oldest hat shop – has been our emblem and is an instantly recognisable part of Wear A Hat Day every year. Wearing a hat reminds us of those who have been personally affected by this devastating disease and helps spread awareness of our cause.
This year’s Wear A Hat Day is supported by Novocure.
