A day at the races is one of the most exuberant days you can dress for. People flock to the race venues – York and Thirsk, Ascot and Aintree, Cheltenham and Epsom – from around the country, sipping Pimm’s on the train as they pile on in their finery for a day of excitement, tension, and fun. Choosing a name, betting on the horses, and backing a winner might be the highlight of the day, but it doesn’t hurt to look good while you’re doing it. So, what does one wear for a day at the races?
