The new star of the races, model and The Block winner Elyse Knowles ensured all eyes were on her when she swept in to Flemington on Tuesday morning.
Elyse looked radiant in an on-trend sunshine yellow top and pants, which she wore with one of the biggest trends of the season – a giant hat.
She accessorised her look with sandals and a boxy clutch, with many on Instagram praising the star for her spring-inspired take.
Rachael Finch also impressed, as she plumped for a Elliatt red dress and Lady of Leisure fasincator, wearing her hair loose and in curls.
Miss Universe Australia, Olivia Molly Rogers, hit the sartorial high notes, wearing a Bronx and Banco floral dress, Viktoria Novak crown and statement earrings and drawing countless plaudits for her beautiful look.
Meanwhile, racing royalty Kate Waterhouse went for a cute and preppy look, in a green floral Miu Miu outfit and a cream bow by Nerida Winter.
Dynasty actress Nat Kelly also opted for a safe but tasteful outfit by Alex Perry and Sophia Webster heels, which she wore with a Jennifer Behr fascinator; Bachelorette star Georgia Love (right) wowed in a bright orange pant suit, tapping into countless trends including oversized ribbons, pant suits and bright colours

What is unacceptable race-wear fashion?
The Cup enforces a strict standard of dress code on the day, with sports shoes, thongs and gumboots unacceptable in the members sections.
Jeans, tracksuits and leather pants aren’t suitable for women and shirts with no collars aren’t welcome on the gentleman either.
Shorts, playsuits and garments which show a midriff are also a huge no-no.
Men are asked to wear a suit with a tie and jacket, but are able to remove said jacket once summer begins.
Elsewhere, Tegan Martin’s outfit was reminiscent of the dancing girl emoji, as the star looked stunning in a red dress by Cooper St Clothing, along with a custom-made headpiece by Ford Millinery.
Lauren Phillips also impressed in a bespoke Forever New yellow dress.
In the played-it-safe-but-paid-off camp, fashion designer and Balinese princess Lindy Klim wore one of celebrity stylist Donny Galella’s top spring racing trends of the season, bold colours.
‘This season we will see both bold vibrant tones like red, purple, yellow/mustard, orange, cobalt blue and lots of pastels especially lilac and pastel millennial pink,’ Donny said.
Dynasty actress Nat Kelly also opted for a safe but tasteful outfit by Alex Perry and Sophia Webster heels, which she wore with a Jennifer Behr fascinator.
Bachelorette star Georgia Love wowed in a bright orange pant suit, tapping into countless trends including oversized ribbons, pant suits and bright colours.

More than 100,000 people are expected to descend on Flemington on Tuesday where they will enjoy countless glasses of Champagne, catwalk shows and friendly bets from mid-morning.
Meanwhile, the excitement can be felt around the country, with plenty in Sydney and elsewhere lining up to place a bet from 9am.
The race that stops a nation will commence at 3pm AEDT.
