As day two of the Grand National gets underway, thousands of ladies dressed in outrageous or elegant outfits as they compete in the style stakes and take in some high-class racing throughout the day. The popular event has seen over 45,000 descend on Aintree for the perfect build-up ahead of Saturday's main event, the Crabbies Grand National. Seven races make up the day as they saw Saphir Du Rheu, ridden by Sam Twiston-Davis, take home the Betfred Mildmay Novices' Chase and following up from his second place at the World Hurdle at Cheltenham festival. A.P McCoy rides Don Cossack and Eastlake in what is his last ever Grand National festival, as he looks to leave the racing scene and his legacy with a bang. Side boob alert!

Along with low-cut dresses, the clunky platform shoes that have become a Grand National staple in recent years were very much on show as were some unflatteringly tight get-ups. Most, however, were simply intent on enjoying the sunshine and, in some cases, the revels with many opting to start their day with a mini bottle of champagne, quaffed with the help of a booze funnel. But while many joined in with the fun, the sight of so many early morning drinkers has left bookmakers panicking at the prospect of a bumper payout following Coral's decision to offer odds on such wardrobe malfunctions as falling over while drunk and showing off too much cleavage. 'If some of yesterday's outfits were anything to go by, we're in for a treat today for Ladies' Day at Aintree,' said Coral's Nicola McGeady, whose company has priced falling over at 1/2 and exposed breasts and bottoms at 2/1.

'With the sun shining down, we're predicting the hemlines to shorten and the necklines to deepen so we could be in for a big payout by the end of the day if our odds are anything to go by.' Such episodes are something Aintree bosses had hoped to avoid this year, with the strict style code just one of a raft of measures designed to add some class to the image of the event which has suffered in recent years. Along with expecting 'Chanel-inspired' get-ups from female racegoers, the management has also threatened to kick out any photographers caught taking photos of drunken racegoers. 'Our event is full of character, it’s fun, and that’s generated by the personality of the Liverpool people,' said Aintree managing director John Baker in the run-up to this year's event.
