OUR most fashionable fillies have arrived at the Melbourne Cup after braving early wake up calls to tease their hair and get their race day make-up on.

Nailing trackside fashion so far are Nikki Phillips and Julie Bishop - we know that sounds odd, but check out these pics:

Now we know she's a supermodel, but we must give a shout out to Megan Gale, who looks fantastic in this sexy red Victoria Beckham dress.

Also looking good in classic black and white were Home and Away's Demi Harman, and The Bachelor's Louise Pillidge, who appeared with Blake in tow.

Bec Hewitt was snapped looking very matchy-matchy in fluoro yellow, and we aren't too sure about model Ashley Hart's fashion choice either.

Gabi Grecko also looked....interesting in a Game of Thrones-esque getup, which could only be trumped by a Birdcage engagement for her and Geoffrey Edelsten.

While the race that stops the nation doesn't start until 3pm, among the first to arrive mid-morning were Kris Smith and cat-eared girlfriend Maddy King.

They were closely followed by Channel Seven's Francesca Cumani, who combines work and play so expertly that one of our journalists was compelled to write this ode.

Posing for photos at the Emirates Marquee, Gigi Hadid looked pretty in pink.

While Myer ambassador Laura Dundovic looked stunning in By Johnny, we're not too sure about her headpiece - it reminds us of Lara Bingle circa 2013.

Frances Abbott also donned By Johnny, and Mel Doyle sported a Scanlan Theodore dress with a Carolyn Unwen headpiece.

We have to admit though, we are a little underwhelmed by Anna Heinrich's outfit choice. She posted this snap on Instagram of her blue Alex Perry dress and Viktoria Novak headpiece:

It's Melbourne Cup, Anna! We wish you'd gone all out like this punter:

Ms Heinrich was among the first to give a sneak peek at her race day look, Instagramming a picture of her hair all done at 7.30am this morning which took two hours to create.

"5:30am start @toniandguyau it's tough being a girl," she wrote alongside a picture of her up-do.

Many other celebrities also took to social media to share their race day prep, with poor Andy Lee getting an inconvenient surprise when he pulled on his suit jacket this morning:

The Stenmark twins also got in on the mirror selfie action, rocking some pretty colourful suits.
