You can pay a celebrity to turn up to the races but apparently you can't make them wear what youhad planned, as Myer learned on Cup Day.
International guest Paris Jackson, the daughter of the late Michael Jackson, was widely tippedto wear Alex Perry to attend her first Melbourne Cup, as a guest of the department store and the Victoria Racing Club.
But when she arrived at Flemington about 12.15pm, she was wearing a rust-coloured dress by Morrison, which is also stocked at Myer, a headpiece by Ann Shoebridge and ankle boots.
According to sources close to Myer, Jackson wasn't a fan of the Perry option and instead opted for the rusty-coloured dress with ruffles and sheer sleeves.

Jackson also reportedly wanted to wear cowboy boots but was encouraged to wear something more dressy, so she settled on a desert boot with a block heel.
A Myer spokeswoman said Jackson had several Cup options, including Alex Perry, to choose from.
Several earlier reports said Jackson was wearing "custom Alex Perry" on Cup Day, but her management said on Tuesday the collaboration never eventuated.
It's the second "wardrobe malfunction" for Myer this carnival, with Jennifer Hawkins arriving on Derby Day in the same Jonathan Simkhai dress as Channel Seven racing commentator Francesca Cumani.
Both women took the clash with a sense of humour, with Cumani posting a "face palm" Instagram post after the coincidence was spotted.
Jackson, who has a signature bohemian fashion style, was expected to spend a few hours in the Myer marquee, as well as fulfil her obligations to the VRC by visiting its new marquee, 1 Oliver St, and watching the Melbourne Cup with VRC chairwoman Amanda Elliott.
It is the first time Jackson, 19, has visited Australia.
