The DO'S and don'ts of how to behave at Royal Ascot this week has been revealed from etiquette expert Philip Sykes.

Ascot Racecourse is hosting one of its largest race meetings this week with thousands of people expected to attend.

The event will see people dress in their finest glad rags but there are strict protocols to follow at the 'posh event'.

Philip Sykes spoke to the Racing Post ahead of Royal Ascot this week to help those attending know what is the correct way to dress and how to conduct yourself.

The founder and principal of the British School of Etiquette has outlined the dos and don'ts when planning a day out at the races.

The Royal Enclosure

This is the premier enclosure, and you need to adhere to the dress code within almost an inch of its life.

Ladies' shirts should be of modest length. The tops should have straps of one inch or greater; strapless, off-the-shoulder or halter neck tops are absolutely not permitted.

Jackets and pashminas may be worn over them. Midriffs should always be covered. Jumpsuits are also welcome in the Royal Enclosure but must fall below the knee.

Hats should be worn. However, a headpiece with a diameter of more than 10 cm (four inches) is acceptable as an alternative. That rules out fascinators.

Gentlemen have a strict dress code as well. You can wear black, grey or navy morning dress which must include a waistcoat and tie (no cravats or bow ties), with a black or grey top hat and black shoes worn with dark socks.

You must only remove your top hat when in a restaurant, a private box or on a terrace. Coloured ribbons on the bands are not permitted in the Royal Enclosure. And novelty waistcoats and ties are definitely out.

How To Blend In

Get off your phone. Take pictures but put your phone on flight mode. Embrace the day! Be vigilant and don't litter. It's a question of being respectful! Being fashionably late is not a thing. If you've been invited to one of the lovely enclosures or have a table booked at one of the amazing restaurants or terraces, then punctuality is absolutely crucial.

What To Do If You See A Royal

If you're lucky enough to meet a royal in person, it is poor etiquette to make the first move, so don't shake hands unless they extend their hand as a welcome to shake hands with you.

In terms of greetings, if you are addressing them in the Royal sense, it’s, “Good Morning, Your Majesty” or “Your Royal Highness”.

The Dos and Don'ts of Ordering Drinks

With the event falling in British summer horse racing season, it lends itself to sparkling wine, Pimm's and Lemonade and gin and tonic. Light drinks- no heavy reds and it's not a cocktail frenzy. If you do choose a lager, don't drink it out of the bottle!
