One of the runners up, Ciara Murphy, a Store Street garda, was delighted to step out of her uniform and get glammed up for the staple event of the Irish racing calendar.
"I love style and fashion and this is a good way to express yourself," she said and added that her colleagues would be cheering her on.
She said her outfit was "all high street brands".
"This is my second Ladies' Day so I am delighted with the outcome," Ciara added.
She admitted there's a contrast between her work on the beat and the glamour of Ladies' Day.
"This is a far cry from Store Street but there is no better place to be," she said, referring to the busy city centre station.
Rachel Coyne from Mullingar also made the top three for her last-minute outfit.
"I really, really just threw everything on this morning - it was a last minute decision so I'm delighted," she said.
Winter style is all about wrapping up and having fun with your look, according to fashion guru Sonya Lennon.
The stylist was on hand to give out the prize for the best-dressed lady at Leopardstown racecourse yesterday.
The former Off the Rails presenter was on the lookout for women who were dressed appropriately for the frosty weather and who wore their outfits with confidence.
"They had to take ownership and looked like they belong, that you're the centre of attention, not the outfit," she told the Herald.
Looking good enough to catch the judge's eye didn't necessarily mean high fashion, however.
"The group we gathered together were quite different, some are dramatic, some are casual," she noted.
Geraldine Shalvey (54) from Foxrock nabbed the prestigious prize and a €5,000 Harvey Nichols voucher for her grey and coral get up.
The stylish public servant sourced almost her entire outfit locally making the most of her villages' boutiques.
"I always put a bit of effort into it," she said.
"I love style and I like different and quirky things. Olivia Palermo would be one of my style icons.
"She always gets it right."
She wore a maroon rabbit fur stole over her grey winter coat. Though she tries not to wear real fur very often, she said this particular outfit needed something to make it pop and the stole was the only thing she found worked she said.
Her hat was custom-made by Dublin hairdresser Anthony Murray.
