The great hat day of French racing: France Galop calls it 'the pinnacle of French elegance' and 'a chic and glamorous Garden Party', with a giant picnic and an elegance contest in which the hat is the star.
what to wear
France Galop: 'pull out all the stops with a chic outfit, or even a daring one... nothing is too eccentric at the Prix de Diane Longines. Don't forget to wear a hat, the must-have accessory... Whether designer, small, large, ornate, extravagant, original or personalised, all styles are welcome.' No measurable rules are set.

Outfits built to this dress code
7 outfits for women and men, with the reason each one passes.

About 13–23°C; usually dry and sunny but showers are possible.
Run since 1843; 2026 was the 177th edition. FashionUnited (2018) reported about 300 contest entrants, many of them professional milliners.
