A wet weather lead-in left many believing the Golden Slipper's must-have accessory would be an umbrella, but as the sun shone down on Rosehill elegance was the theme of the day.
Punters from across the nation descended on the racecourse on Saturday to watch the world's richest race for two-year-olds and to witness champion Winx take out her 32nd straight win.
Olympic swimming champion Cate Campbell posed for photos in a striking black Carla Zampatti jumpsuit, paired with a gold headpiece from Mimco.
Despite being more at home in the pool, Ms Campbell had plenty of trackside style tips on hand - most important she says is making sure you stay elegant throughout the day.
"Wear something comfortable ... go small heels or block heels because probably the worst fashion mistake is to take your shoes off halfway through the day," she laughed.
The elite athlete was on hand as an ambassador for the Australian Turf Club's 'Toughest Champion' campaign.
"It's really just to get people to think differently about jockeys and see them as the incredible athletes that they are," she told AAP.
"The jockeys have to be really fit and really tough to hold onto a 500kg horse running at 50 km/h and to be in control of that horse - there's a lot of strength required but also a lot of mental strength as well."
Also at Rosehill was The Rubens frontman Sam Margin and model partner Rosie Tupper who cut a stylish swathe through the crowd, the latter wearing a custom made Lillian Khallouf pink tweed dress with a black Nerida Winter hat.
It was Ms Tupper's first ever time at the races and she said when it came to tips on what to wear, there was a common theme to the advice.
"Less is more, that's always my thing," she told AAP.
"Classic, elegant."
It was that appreciation for elegance that prompted Ms Tupper to choose 51-year-old Margery Myall as the winner of the Longines Prize for Elegance fashions biggest gong on Golden Slipper day.
The Brisbane former academic and accountant turned fashion creator wore a cropped patterned suit that she bought off ASOS paired with a gold floating feather headpiece by Rachel Black.
"I believe it's a case of it's not what you wear, it's not what label you wear it's how you wear it," she told AAP.
"I do enjoy fashions do I believe you can spend a lot or a little but it's really about how you wear it."
