Pia had started prepping for ‘the race that stops a nation’ at 9am when she sat in the stylist’s chair for hair and make up. 

She had her styled in loose waves by Maria Uva and opted for a timeless smoky eye and nude lip for her make up by Chantelle Baker. 

The 34-year-old actress flaunted her hourglass figure in a tight forest green dress that featured a net-style hemline that showed off her long, lean legs. 

Featuring a flash of white, the skirt shimmied as she walked.

Pia’s accessories were simple and chic.

Opting for classic black pointed pumps, thin gold hoop earrings, a black wide-brimmed hat and large black sunglasses. 

Her small shoulder bag, which featured patch detail reminiscent of a Mondrian Composition, added a dash of interest to her look.

But her most dazzling addition was her engagement ring, a custom-made brilliant cut diamond with diamond shoulders set in a 18-carat gold band. 

Tyson presented Pia with the ring from Bensimon Sydney, which is located in Darlinghurst, on Saturday when he popped the question.

Pia is named among the upmarket clientele of diamond merchant Ronnie Bensimon, who also designed the promise ring Sam Wood presented Snezana Markowski with on The Bachelor.
