While last year's Fashions on the Field winner, Canberran Angela Menz, mingles in Myer's VIP Birdcage marquee, Hall resident Trish McIntyre will be meeting the Prince of Wales and the Duchess of Cornwall at lunch in the Victorian Racing Club Committee Room.

Ms McIntyre is one of three people chosen to meet Charles and Camilla at precisely 1.55pm on Cup day.

The royals have asked to meet some of the racing industry's volunteers and people who contribute to the community through their charity work.

Ms McIntyre, who works with the National Jockeys' Trust raising funds and awareness for injured jockeys, was nominated for her 25 years' service to a number of organisations including the Starlight Children's Foundation and her support to blind dressage champion Sue-Ellen Lovett.

She is hosting a lunch in Melb-ourne on Monday for the trust.

For Cup day, Ms McIntyre plans to bring her own flash of colour to Flemington on what is forecast to be a cloudy day in a Gloria Grady Design dress with flecks of yellow, orange and royal blue, a mint peplum jacket and a large orange hat finished with a handmade silk flower.

She said her briefing ahead of the royal lunch was nothing out of the ordinary except for the lack of attention to dress code.

''The protocols are well and truly there, no cameras, no photos, no mobile phones, but at Royal Ascot ladies have to have the same colour jacket and skirt, no open shoes … and dresses just to the knee, where here there is no protocol, so I assume they just trust us.

''Australian girls dress very well so we don't have to be told,'' Ms McIntyre said.

Also in Melbourne before race that stops a nation is Angela Menz who is preparing to relinquish her mantle as Fashions on the Field queen.

Ms Menz, speaking to Fairfax after meeting milliner Philip Treacy and taking a peek inside Myer's feminine and floral marquee, said Ms McIntyre would be looking fashion forward for her royal encounter in her choice of peplum jacket and splashes of bright colours.

The 28-year-old Canberran has made a sartorial splash on the national racing scene since she was judged the national winner of last year's Fashions on the Field competition by designing and making the majority of the bold outfits and unique accessories she combines for race days.

''I push it to the extreme sometimes but that's what it's all about, interpreting race-day wear and adding a high fashion element.

''I'm bringing pom-poms back this year. Expect to see pom-poms at the Melbourne Cup,'' she said.
