Before 1952 military dress was 'de rigueur' in all Olympic equestrian events as all riders were commissioned officers. It is still common to see riders in formal military dress - with traditional hat or helmet. Here Andreas Ostholt of Germany rides horse Rainman during the Eventing - Dressage at Sha Tin Venue for the Good Luck Beijing test event for the 2008 Summer Olympics. Rainman is being ridden in a full cheek snaffle with a flash nose band.
