Thousands of people are preparing their flamboyant frocks and fascinators for Sydney spring carnival's most glamorous event, but official milliner Nerida Winter says it is the little things that will catch the judges' eyes.
Winter, who has been the official milliner to the Australian Turf Club since 2003, says she expects to see feminine ruffles, lace and pastels, and structured 80s shapes as big trends at the Moet & Chandon Spring Champion Stakes Day at Randwick on Saturday.
"Don't forget that the races is all about the wonderful sport of horse racing - get involved, dress in your finest daywear and have fun," Winter told AAP.
Despite the focus on frocks, it's the accessories such as jewellery, shoes and quality fascinators that will turn the judges' heads, she said.
"It's all about attention to detail and accessories are the perfect way to express your sense of style."
Winter said while creativity was the key to winning, racegoers should choose quality craftsmanship when it comes to fascinators and "avoid the DIY look".
Models and spring carnival ambassadors Natalie Roser and Georgia Fowler will be joined by photographer Sonny Vandevelde to judge both male and female finalists as they parade their outfits in front of the main grandstand on Saturday.
With prizes totalling more than $75,000, including a BMW 220i Convertible valued at over $65,000, racegoers will be sure to follow Winter's advice.
