Sophie, Countess of Wessex, became the first royal to experiment with Ascot's newly approved dress code by wearing a formerly-banned jumpsuit in the Royal Enclosure last year. And for her appearance at this year's event, the royal tried out the style once again.
In 2018, the countess' wide-legged Emilia Wickstead jumpsuit featured flowing culotte trousers - which meant it could easily be mistaken for a dress - short sleeves with contrast detail, and a pleated bottom.
Clearly a big fan of the jumpsuit, Sophie opted to wear a navy all-in-one (also by Emilia Wickstead) for her appearance at Ascot this year.
As of 2017, Royal Ascot's Style Guide confirmed that the contemporary item of clothing had been "welcomed as acceptable" for the Royal Enclosure.
"Ascot continues to recognise key trends in the ever-evolving world of fashion," the guide added.
However, last year, the Ascot dress code made headlines when organisers banned Bardot off-the-shoulder necklines.
When the official fashion guidelines were released back in March, they confirmed that bare shoulders were not permitted in several of the enclosures, along with spaghetti straps, halternecks, and strapless styles, which were already banned from the Royal Enclosure.
Additions to the official dress code in 2018 also made socks a requirement for gentlemen.
