She's had a tumultuous year with the imprisonment of husband Oliver Curtis and radiation treatment for breast cancer.

But on Tuesday, Roxy Jacenko looked the best she ever has, cutting a radiant and stunning figure, as she hosted a Melbourne Cup luncheon for her staff and Sydney's elite at Woollahra Hotel.

The 36-year-old sported an abstract floral Peter Pilotto frock that drew attention to her bronzed complexion and svelte physique.

Roxy was dressed to impress in designer labels from head-to-toe.

A round-neck abstract floral frock by Peter Pilotto skimmed over the entrepreneur's lean frame, with the fabric flaring out from the hips down.

Elongating her frame with a pair of Azzedine Alaïa heels, Roxy accessorised further with a gold statement watch and stunning burgundy and white floral headpiece by Myra Perezl.
