But the long white thermal underwear she wore under her costume, and the jacket which she donned shortly after hitting the stage, was the evidence that this was no ordinary show.
After playing in lashing rain in Cork the previous evening, Dolly performed her second outdoor gig in as many nights in less-than-perfect weather conditions.
It was a sign of the times that the queue for the coffee cart dwarfed the line for the beer tent, as temperatures plummeted and freezing fans tried to get their hands on something warm.
Dressed in platinum blonde wigs, pink cowboy hats and sparkly shirts - and that was just the men - the hallowed grounds of Nowlan Park were well and truly trodden as 20,000 impatient fans milled around waiting for the off.
Delayed by an hour due to "technical problems", the atmosphere waned as the temperature dropped.
But in the freezing cold weather and raging winds, Dolly and her legion of 20,000 dedicated fans braved the elements to have their night together.
Throughout the course of the evening, the singing sparrow turned her hand to a multitude of instruments, including her guitar, piano, slide guitar, banjo and even a tin whistle.
Belting out hits from across her 40-year career, she played to the crowd with all-time favourites "9 to 5" and "I Will Always Love You", leaving plenty of time to plug hits from her new album, the aptly-named Backwoods Barbie.
But she drew the biggest reaction from the crowd with "Joelene" - introducing it as a true story about "a red-haired Irish girl".
"I still think about Joelene a lot," she cooed to the crowd.
"Especially when my husband is stretched out asleep in his Lay-Z-Boy and I sometimes wish she'd come and take my man."
She kept up a lively banter with the crowd between songs, even holding a running commentary every time she turned to blow her nose because of the cold.
The show, which replaced Nowlan Park's popular Source Festival, was heavily hyped, promising "all new production including screens, sets and costumes" and the lack of support acts put down to what was supposed to be an extravagant stage show, so fans were surprised, and a little disappointed, at the modest show put on by the woman who is famous for her outlandishness.
With just an empty stage and two video screens, there was none of the expected theatrics, colour or pizazz which have come to be synonymous with the Smoky Mountain Songbird.
