So the news that Kristina Rihanoff of Strictly Come Dancing fame was escorted away from the enclosure on the second day of Ascot race is hardly surprising.
The rules continue with a note that "strapless, off the shoulder, halter neck and spaghetti straps are not permitted, and midriffs must be covered."
The dancer was seen later on in the morning wearing a knee-length shift dress with a blazer and the same statement rose-coloured hat by London-based designer Ben De Lisi and it turns out? Kristina wasn't actually told to leave - her first outfit was merely part of a promotional stunt.
"It was always her intention to change her dress and she is still at Ascot enjoying the hospitality at the races," her spokesperson told the Daily Mail. Her Twitter page proves this too.
