Derby Day: What the biggest celebrities are wearing on the most stylish day of the year.

It’s the most fashionable time of year, and on the first Saturday of the November Spring Racing carnival, Australia’s biggest names turned out for the most stylish day of the most stylish time of year.

Sorry to be predictable, but our ‘best on grounds’ definitely go to Jennifer Hawkins and Kate Waterhouse.

All of the ladies looked gorgeous. Take a look for yourself.
