Prix de Diane Longines: where horses and hats take center stage

A historic event blending elegance and prestige, the Prix de Diane Longines returns June 14 at the Chantilly Racecourse. While purists thrill to the races – three-year-old fillies competing over 2,100 meters – most attendees come to see and be seen, admiring the season’s most extravagant hats and ensembles. The much-anticipated elegance competition remains a highlight of the day, alongside the refined Ladurée picnic served in a collectible hatbox. Festivities continue throughout the Village de Diane and the Folies de Diane, a trackside space offering surprise activities and DJ sets between races. And as the sun sets, the celebration carries on with the Prix de Diane Longines after-party, where guests dance beneath a dazzling disco ball until 9:30pm.
