Hurrah, Royal Ascot week has officially started! Today's racegoers have set the bar for fabulous occasion wear, floral headgear and stylish accessories - and it's not even Ladies' Day yet.
HM the Queen, Prince Philip, the Duke and Duchess of Cornwall, Prince Harry, Princess Beatrice and Princess Eugenie all turned heads during the first Royal Procession of the week.
While the Queen looked beautiful in a pastel blue button-down coat over a blue and white print dress with a matching floral applique hat, the princesses were also the epitome of race day sophistication.
Princess B opted for a blue lace dress and wide-brim hat while Eugenie went for a lightweight nude coat with matching pillbox design and ankle-strap heels.
As for the ever-dapper Prince Harry? The 29-year-old royal sure knows how to pull off a top hat, as well as a navy suit and powder blue print tie.
Trends from day one included floral dresses, bright colour blocking, gorgeous updos and fancy feather hats with fascinator detailing.
As to be expected, the headgear styles weren't exactly subtle - peacock feather headdresses and oversized lily pads, butterflies and present boxes have all featured so far.
