It's one of the most fashionable days of the year and there'll be a stunning array on display for Ladies Day at Down Royal today for the Best Dressed Ladies competition.
Entrants will be scrutinised by Irish Independent fashion editor Bairbre Power and model Vogue Williams, who's married to former Westlife singer Brian McFadden.
Judges will seek "an outfit that is not only elegant in style, but that reflects the character of National Hunt racing combining both the classic functionality required for winter racing with an individual touch".
The winner will receive a racing experience for two people in Dubai, including three nights in a five-star hotel. Five runners-up will receive vouchers for dinner for two in Belfast's Mourne Seafood Bar.
