A group of six deeply tanned women were spotted at the entrance of the royal race course, posing for photographs wearing skintight blue all-in-ones that looked for all the world like futuristic smurf suits.
If that wasn't enough to make the Queen blanch, the sextet were handing fliers and stickers to local strip club Tantric Blue to bemused racegoers as they entered the grounds.
Thankfully for the delicate constitution of the more genteel guests (but no doubt to the disappointment of others), the lycra-clad women were quickly dispatched by officials who disapproved of the scantily clad women promoting the so-called gentleman's club outside the event.
Tantric Blue, which claims to be the largest club of its kind outside central London, is based in Heathrow, on the borders of Surrey, Berkshire and London, and boasts of its 'upscale adult entertainment'.
A spokesman today said the girls were 'made up' at being able to join in the fun today.
'They made their blue catsuits two weeks ago to get ready,' they told MailOnline. 'They looked really striking - I'm not surprised they caused a stir.'
Not on your nelly! A group of promotion girls handing out fliers for local strip club Tantric Blue attempted to enter the grounds - but were quickly dispatched by officials'We have a love-hate relationship with Ascot,' said Tantric Blue manager Annmarie Harris. 'We love them, but they don't like us! They have a certain dress code and our dress code doesn't meet the criteria.
'But we really don't mean to offend anyone. We come every year for a bit of fun. We have great banter with the security when we are there. They understand it's great titillation for the crowds - it's all harmless.
'We didn't realise when we had our catsuits made that the dress code has been changed and ladies were no longer allowed to show their shoulders. They must have thought "Jesus Christ!" when they saw us coming up the road.'
'But we all love going to Ascot and meeting everyone. It's really nice place to be. We are very blingy this year - we've had lots of comments from everyone, but they've all been really flattering. We were interviewed by the racing reporters to go on television too, which was really exciting.'
Giving racegoers the blues: The girls, who were doling out the risque promotional material to Ascot racegoers outside the grounds, were drastically underdressed for the genteel occasionInside the course, an immaculate team of 60 young women (with a few young men thrown in) in uniforms of purple linen dresses and jackets from High Street store Hobbs, along with Ilda Di Vico hats, enforced the new dress code for race goers.
The fashion officers – who preferred to be called ‘dress code assistants’ – prowled the entrances carrying baskets packed with colourful fascinators, pashminas and ties. Guests who fell short of the dress code for the grandstand were given appropriate attire for free.
Meanwhile, anyone heading for the royal enclosure who had failed to bring a hat was ushered discreetly to an office in which there was a huge array to choose from for a £50 deposit. However, as no identification was taken, one assistant admitted she was ‘not that hopeful’ of getting them all back.
Despite the kerfuffle outside the course, Ascot’s head of communications, Nick Smith, declared himself ‘delighted with the standard of dress’.
He said: ‘We always said that we would adopt the new rules sensitively, using common sense and discretion, especially in the first year, and that is what we are doing.
‘The most important thing is that people have an enjoyable time.’
'Just as people did on the opening day of Royal Ascot, everyone seemed to really enjoy dressing to their best and were treated to a great day's racing,' he said.
'We didn’t quite have a Royal winner, but it was fantastic for everyone here celebrating the Diamond Jubilee to see The Queen’s Carlton House run a tremendous second in the Prince of Wales's Stakes. She has another chance tomorrow with Momentary who will be ridden by crowd favourite Hayley Turner.'
