It was a day of royals, rain and, of course, more fabulous fascinators at the Royal Ascot.
Aside from being Ladies' Day at the races, it was also a big day for Carole Middleton, who arrived in a horse-drawn carriage as part of the royal procession with Queen Elizabeth.
the Duchess of Cambridge
's mother donned a subdued champagne colored suit and matching hat, while the Queen opted for a cheery pink hat and suit. After her Philip Treacy creation
caused a stir at the royal wedding, Princess Beatrice chose to play it safe in navy blue number.
The rainy day didn't keep other race-goers from breaking out their best headpieces
. Everything from balloon hats to black swan fascinators were on display.
It's been busy couple weeks at the races for the royals
. Earlier this month Prince William
and his bride attended the Epson Derby
, where they cheered on the Queen's prized horse.
