It was an evening of glamour and razzmatazz for the debutantes of Santa Sabina in Sutton for their Oscars-themed debs night.
The red carpet was rolled out as parents, teachers and past pupils gathered in the school's reception area early in the night.
"It was nice being back in school and not wearing a uniform," former head girl Laura Gavagan said.
The style was a mix of vintage and classic as floor-length gowns from Cari's Closet proved popular with many debutantes while others opted for a more for stylish Folkster dresses.
The gaggle of debutantes enjoyed a glass of buck's fizz and posed for pictures, before climbing on board buses to take them to the Headfort Arms Hotel, Kells, Co Meath.
After a champagne reception, guests made their way into the grand ballroom for a three-course meal.
It wasn't long before five-piece band Catch 22 took to the stage and started belting out rock and pop songs.
"The band were fantastic and got everyone dancing," Laura said.
The students then set about presenting Debs Awards, inspired by hit TV show Friends, with the Chandler Award (Funniest Person) going to Terri Kelly- McDermott.
Old photos of students dating from first year were projected onto a wall evoking feelings of nostalgia.
Around midnight, the action moved out of the ballroom into the hotel's nightclub where the former pupils threw some serious shapes.
As part of Santa Sabina's graduation ceremony in May 2015, the students choreographed a dance routine to a "mash up" of popular songs, including Uptown Funk and Shaggy's 2000 hit It Wasn't Me.
"We played the song on the Debs night," Laura said. "Everyone got up dancing. It was great fun."
Breakfast was served at 3:30am and by 4am everyone crowded back on to the buses and headed back to school.
"A few people fell asleep on the bus back to school," Laura said.
"It was such a fantastic night and one we'll all remember."
