Winning at the races is nothing new for Olivia Moor.

The best-dressed winner of the Prix de Fashion at the TV3 Derby Day at Ellerslie yesterday has scooped the top prize twice and is a regular at cup events. Moor won $30,000 worth of prizes including a trip to the Melbourne Cup Carnival, two dresses by Natalie Chan, $4500 of Westfield giftcards, Samsonite luggage and $8000 of Thomas Sabo jewellery.

Judge Chloe Moo said Moor's sophistication and attention to detail stood out.

Top colt Puccini took honours in the $750,000 New Zealand Derby.
