The weekend is already in full swing at Royal Ascot as high spirited revellers enjoy a fourth day of festivities in the sun.
Revellers dressed to the nines in their finest frocks, sharpest suits and most fabulous hats posed for the cameras as they descended on the Berkshire racecourse this morning.
While many women plumped for demure sundresses for the occasion, others donned daring frocks complete with plunging necklines and thigh-skimming hems.
Unsurprisingly, statement headpieces were the order of the day for many, with a Union Jack made from faux flowers and a flutter of neon pink butterflies both on show.
Among the early arrivals was actor Chris Quinten, 61, who arrived hand-in-hand with his glamorous fiancée Robyn Delabarre, 21, who stunned in a fitted white frock.

With the clue in the name, Royal Ascot is hugely popular with the monarchy and Her Majesty has attended every year since ascending the throne.
The Queen looked radiant in bright pink as she arrived in the traditional carriage procession.
The Duchess of York is also in attendance and curtsied deeply as Her Majesty’s carriage drove past.
Yesterday the monarch, 93, took in the action alongside several members of the Royal Family including Princess Eugenie, Zara Phillips and Sophie, Countess of Wessex.
The Queen broke with her typical brightly coloured outfits with a pale grey ensemble yesterday – now royal watchers are eagerly waiting to see what she steps out in today.

But for now all eyes are on the hundreds of racegoers making their entrance – with a full spectrum of race day style on show.
Among the early arrivals was milliner Ilda Di Vico, who made a statement in a pleated neon pink frock and an extravagant headpiece adorned with butterflies.
Meanwhile businesswoman Valerie Stark channeled one of Royal Ascot’s biggest style trends in a sharp, tailored suit and a turban-inspired hat.

Others have kept it classic in demure summer frocks. Suits have also proved a popular trend for women.
Visitors to the Royal and Queen Anne enclosures have to abide by a strict dress code, which does not allow bare midriffs or strapless dresses, but for guests in the Windsor and other enclosures the rules are more relaxed.
Up to 300,000 people were expected to descend on the event over the course of five days.
