Royal Ascot. If you have a ticket to Ladies' Day today, lucky you! You probably already have your hat chosen and carefully pinned to your coiffure, but if not, here's Vogue's guide to choosing the perfect chapeau, and anyway, if it's within budget I hope you looked no further than Philip Treacy. In any case, my invitation seems to have been lost in the mail, so I shall be with you in spirit rather than in person, merely keeping track of all the action from the wires. Hooray for hats!
