Step out in your finest attire for the Investec Derby Festival Ladies' Day on Friday 5th June for the chance to win a fabulous Royal Caribbean cruise for two, worth £5,000! TV personality and radio host Vogue Williams, Hello! Online fashion editor Alex Light, and Royal Caribbean Sales Director UK & Ireland Ben Bouldin will be judging the Hello! Magazine Best Dressed Lady competition.The Investec Derby is one of the highlights of the British summer sporting and social calendar and racegoers never fail to impress judges with the range of fashion on display. Whether you want to grab the attention of the judges in an Alexander McQueen-inspired look or prefer the more classic Kate Middleton style, the judges will be looking for racegoers who are confident in their style, and with a Royal Caribbean cruise up for grabs, it’s certainly worth dressing to impress!Vogue Williams commented: “I am absolutely delighted to be invited to the Investec Derby Festival as a guest judge for the Best Dressed Ladies competition. Epsom Downs Racecourse has an extensive history and is known for having an electric atmosphere which I am very excited to have the chance to experience."For the Best Dressed Ladies competition I am looking for someone that not only looks great but has that little something extra that catches your eye. I’ve heard there are also a lot of boutique designers in Surrey, so try not to limit yourself with just a designer outfit, I love to mix and match designer with high street.”Hello! Magazine co-editor Ruth Sullivan said: "It is one of the most glamorous occasions of the social calendar and we are delighted to be involved. We are looking forward to seeing all the winning looks and playing our part in deciding who is first past the post when it comes to style."Vogue Williams will be taking to the decks shortly after the last race on Ladies Day for a post racing DJ party in Camelots Bar within the Grandstand Enclosure.For further information or to book tickets or hospitality, visit www.epsomderby.co.uk or call 01372 477747.
