Top Tip: What the judges are looking for:
Melanie Morris says...
Melanie Morris is editor of Image magazine
"The Races Ball was a Galway institution for about a decade, held on the Friday night at the Radisson Blu hotel. After a two-year hiatus, it's back – and now even more so! Still on Friday, but now decamped to the g's brand new function suite, this year's Races Ball will raise funds for ACT Meningitis.
"The early part of the evening will include live racing on the big screen, and the ubiquitous Best Dressed Lady competition, judged by TV3's Sinead Desmond and I.
"We'll be looking for full-on glamour and the winner will receive a €500 gift card from Brown Thomas, and a hat (because remember folks, in Galway it's all about the hat) by local star milliner, Suzy Mahony.
"The perfect end to a magic week."
PJ Gibbons says...
PJ Gibbons, editor and publisher of 'Social & Personal' magazine, is judging at Anthony Ryans Best Dressed competition on Thursday at Ballybrit. "Sophisticated, tailored dresses and skirt suits are ideal choices and rose-hued fashion is about to have another big revival for autumn, and the colour is so well suited to Irish skin tones," says PJ.
"I'm a fan of 1940s-style wide-brim hats but it's important the headpiece, whatever it may be, does not overshadow the outfit.
"And, as always, carefully chosen accessories are what's going to set the contestant apart – so choose wisely."
Heidi Higgins says...
Heidi Higgins, judging at the Ladbrokes' Red Day, says: "I will be looking for an outfit that stands out from the crowd!
"Red is the theme for the day so it could be an outfit in red from head to toe or simply a stunning red accessory that completes the look! Quirky accessories are key for a winning racing look, adding pops of colour. Sensible shoes are advised as it will be a long week in heels – and a fabulous hat for a finishing touch!"
Kathryn Thomas, who will be one of the judges in the Anthony Ryans Best Dressed on Thursday, looks for colour and likes racegoers to be comfortable and not suffer for their fashion. Age-appropriate and weather-appropriate dressing is important too.
Marietta Doran says...
Stylist Marietta Doran is judging Most Stylish Lady at the Meyrick Hotel from 7pm on Thursday evening and also Friday's Fair Lady competition at Ballybrit. "I'll be on the hunt for someone who looks smart with an injection of old-fashioned class," she says. The fashionista confides that for her, matching clutches and umbrellas at the racecourse are a "sartorial no-no".
