Black, white and stylish all over! That was the calling card of the attendees of Saturday's Australian David Jones Derby Day at Royal Randwick. DJs pulled a stellar crowd for the trackside event to the famed Black Caviar race — but we've gotta confess, it was not the world's fastest horse that we wanted to see. It was the frocks! Be it all black, all white, or a monochrome combination; the stylish set clearly checked out our racing dress code guide (or shopped our selections) last week. Megan Gale went head to toe noir in Willow and Nerida Winter, Kate Waterhouse rocked a sleek Gucci number and Suzy O'Rouke hat, Emma Freedman got lacy in Collette Dinnigan with a Nerida Winter topper, and Samantha Harris took a modern approach in a stunning Dion Lee design. Step inside to see who else hatted up for Saturday's super stylin' carnival.
