None of the favourites came through in the Melbourne Cup, but Australian fashion favourites were big winners off the track.
Camilla and Marc, Alex Perry and Ellery were all choices of the Flemington Birdcage's high-profile international stars on Tuesday.
Actress Mischa Barton was statuesque and elegant in a sweeping burgundy gown by Perth-born designer Kym Ellery, New York-based Aussie Rose Byrne chose perennial racing favourite Alex Perry, and US reality TV star Taylor Armstrong went for Natasha Gan because it was "fun but edgy".
Armstrong finished her look with a cream fascinator, a first for the Beverly Hills-based celebrity.
She confided she had no idea if she was wearing it the right way.
"I was feeling this was pretty adventuresome and now I'm looking around and who knew people are wearing the Eiffel tower on their head," The Real Housewives of Beverly Hills star told AAP.
Barton, whose dress was complemented by a dusky-rose Philip Treacy headpiece, gushed about her love of accessories.
"I love jewellery, and Philip Treacy is great. I really wanted to wear this dress because they made it for me and I really liked it," she said of Ellery.
Rose Byrne, like Armstrong, said she had deliberately looked for a local designer.
"I wanted to wear an Australian designer. I just wanted something really fresh and young," she said.
She accessorised her white dress, banded with black and beige, with a black and white Chanel headpiece.
"I wanted to be fun and festive and embrace the fashion side of it because I love clothes."
The Damages actress received the tick of approval from Aussie designer Leona Edmiston.
"She's such a beautiful girl, she couldn't help but look stunning on race day," Edmiston said of Byrne.
Wearing one of her own vintage print dresses and a custom-made Nerida Winter headpiece, Edmiston deemed the day a fashion success, saying she hadn't seen any disasters.
For her, a perfect racing outfit was about the overall look.
"You've got to create just one strong visual impact," Edmiston told AAP.
"Obviously it's got to be day wear, but day wear taken to its ultimate and most exciting form.
"You've got to be a visual delight."
Revenge star Ashley Madekwe was just that in a white and sorbet-green dress by Camilla and Marc.
"I only looked at Australian designers," she told AAP.
"There's a ladylike-ness to the way you dress for the Cup and I was really looking forward to doing that."
Armstrong had a Natasha Gan dress she had selected waiting for her when she stepped off her plane just hours before the start of the Cup.
Fielding media questions in the Lavazza marquee, she said it had always been her intention to pick an Australian label.
"There were some others that I really loved.
"It was exciting to wear something Australian."
