It was a trip down memory lane for those attending the St Andrew's College Debutantes' Ball.
The class of 2015 returned to their alma mater in Booterstown for a red carpet reception hosted by the parent teacher association.
Sweeping gowns in vivid jewel hues and twisted halter necks from Cari's Closet and Pamela Scott were popular with girls.
But the stylish young gents also brought their A-game, arriving in classic tuxedo suits.
Some bucked with tradition; Ross Nicoll, from Greystones, cut a dash in a colourful tartan kilt, while Leo Kevany from Killiney went for a loud printed suit jacket complete with a royal blue bow tie.
The debutantes posed for pictures outside before hurrying into the Senior Hall, which was brightly decorated with the school colours and balloons.
Proud parents milled about while the debutantes and their dates caught up with former teachers and recalled classroom memories.
Once the reception had drawn to a close, students jumped aboard a fleet of coaches and made a bee-line to The Pavilion, in Leopardstown, for dinner and dancing.
Guests were treated to a three-course meal of Caeser salad, chicken supreme and chocolate macaroons.
Once everyone had polished off the dinner, DJ Gary Lonergan took to the decks and everyone hit the dance floor.
"I requested Dancing in the Moonlight by Toploader five times," former Head Girl Serena Brooks said. "Everyone was on their feet and having the time of their lives, the atmosphere was great."
There was plenty of joking, joshing and selfie-taking but in the blink of an eye the sun began to rise and it was time to go home.
"We all enjoyed a breakfast roll around 4am and then we started to make our way home," Serena said.
"It was a fantastic night and so nice to relive memories with friends."
