The Duchess of Edinburgh has one of the most impressive style files in the royal family.
From her timeless and tailored London girl era to her marvellous millinery moments and feminine, floral fits, the wife of Prince Edward's unmistakable elegance often sets her apart from the royal style set.
Where Duchess Sophie, 59, truly excels in the fashion department, is at Royal Ascot - the annual summer season at Ascot Racecourse where horse racing meets sartorial splendour.
Royal Ascot is an opportunity for racegoers to don their finest attire and magnificent hats, with the Royal Enclosure boasting an extremely specific dress code.

Strapless or one-shoulder dresses are strictly prohibited, as are halter necks, visible mid-riffs and customised top hats adorned with embellishments like ribbons or feathers.

The Duchess no doubt caught her boyfriend Prince Edward's eye as she beguiled with a dewy beauty glow, including a soft blush, rosy lips and a light flutter of mascara.
One of the most important elements of Royal Ascot's dress code is the hat - an essential for all guests in the Royal Enclosure - and Sophie's was a bow-adorned, wide-brimmed masterpiece that perfectly accompanied her figure-flattering look.

Continuing her bow theme, on Christmas Day in 2023, the royal mother-of-two wore a green coat, complete with statement bow detailing on the shoulder.
