There is a photograph of the party of George Mallory and Sandy Irvine's 1924 expedition party shordy before their ultimately ill-fated attempt on the summit of Everest,one of the most striking features of which is the clothing worn by the group.They are dressed in what appear to be tweed jackets with long woollen scarves tossed over their shoulders,and could easily be a group of friends about to embark on a Sunday afternoon ramble on the fells.
