The biggest crowd of the week so far has been enjoying the atmosphere at one of the south's biggest social highlights of the year as ladies - and gents - dress up in their finery to enjoy racing, eating, drinking and just being out in the Sussex sunshine to share the experience.
On this page and the ones linked are pictures of some of those attending - if you are there, see if you have been snapped! We'll add to the gallery throughout the day. Feel free to send us your own pictures - email them to [email protected] or tweet them to @stevebone1
