Oaks Day may be known as Spring Racing Carnival's Ladies Day, but ladies and gents alike dressed in a rainbow of finery at Flemington Racecourse on Thursday.

If Derby Day is for sleek black and white, and Melbourne Cup Day is for the fearless, then Oaks Day is a chance to make your flair for fashion known.

The third day of the Spring Racing calendar was a sunny one, and racegoers experimented with pattern, texture, vibrant colour and shape, as captured by Broadsheet photographer Rez Harditya.
