Stylist Lana Wilkinson, who wouldn't have looked out of place at the top of an altar, turned heads in an OTT, off-the-shoulder, pink tulle Toni Maticevski dress.
Rebecca Harding, who is currently dating Andy Lee, pulled out all the stops in a blush pink Balenciaga dress with black gloves and headband.
The Bachelor star Anna Heinrich, who has denied a split from her husband of one year Tim Robards, usually dresses to impress, but she dropped the ball on Oaks Day in a Forever New blue lace dress that peaked in 2014.
