Video. Big hats, celebrities, champagne and horse racing... It's Ladies Day at Ascot!
And as well as being a festival of fashion, The Queens horse Estimate was also running in the Gold Cup.
Last year, her Majesty's horse won the race, but it wasn't the case today. Instead it was the turn of the favourite, Leading Light, to shine.
But it wasn't all about the racing. For many of the 40,000 people who attended today, its also about getting dressed up!

Race goers at Royal Ascot will have to get their hats at the ready and dress to impress, as it's Ladies Day! The public will attend in their thousands, though at least one racing pundit says it's all about showing off.
Fabulous frocks and heavenly hats are on display for Ladies' Day at Royal Ascot. Fashionistas, though, are hoping nothing rains on their parade! The weather doesn't look too good!
This year's dress code has been tightened up - bare shoulders and thin straps are a no-no. Hats or headpieces are mandatory.
About 300,000 people are expected to attend Royal Ascot - consuming 170,000 bottles of champagne, 10,000 lobsters, 5,000 oysters and 18,000 punnets of strawberries.
It's Ladies Day at Royal Ascot - the most flamboyant day in the racing calendar - but with heavy rain forecast, it's likely umbrellas will join the eccentric hats on show today. Up to 300,000 race-goers will attend the event which runs until Saturday.
