Horsey folk – Few of us will ever get to attend a posh polo event, but if you are lucky enough to be invited to a top equestrian event you will need to know what to wear and how to behave.
Tread carefully – Treading the turf at a polo match is something everyone is expected to do, says Celestria Noel, a expert on the rituals and manners expected at Britain's swanky social events. "It would be a faux pas to say: 'oh, why should I do something so menial,'" she says. "Women should wear wear wedges or flat shoes -- it's a faux pas to wear high heels." Clearly no one told the women in this image who were attending the Veuve Clicquot Gold Cup at Cowdray Park in West Sussex.
A breed apart – Queen Elizabeth II always presents the prizes at the Cartier Queen's Cup at Guards Polo Club near Windsor. The British Royal family are great supporters of equestrian events.
Champagne lifestyle – Contrary to popular perceptions, polo matches are not all champagne and caviar occasions, says Noel. "Most polo is very, very casual and not a great spectator sport. But two or three times a year there are big social events which are the finals of major tournaments."
Posh nosh or greasy grub? – Spectators at this year's Badminton Horse Trials enjoy a bite to eat during the six day event in Gloucestershire in the west of England. "At most horse trials it's a burger van, a sit-down tea or anything like that," says Noel. "There isn't any particular etiquette."
Blood lines – Princess Anne is a great supporter of British equestrianism. Her 200-acre country residence, Gatcombe Park, regularly hosts eventing competitions.
In the dog house – Noel says one of the worst faux pas you can make at a horse trials is to let your dog off its lead and out of control. "You'd get into a lot of trouble," she says.
Don't frighten the horses! – There are plenty of ways to put a horse off its task, so beware of making sudden movements and wearing inappropriate clothing or accessories -- like jangly bangles and things like scarves that could fly off suddenly.
