There were dances and drinkies and dozens of damsels in dashing dresses and dapper dudes in their divine dining jackets.
Indeed, a lot of 'D's during the DIY Art Deco Weekend which drew hundreds of visitors to the Bay, and which left many of them, along with locals, with big smiles after a 45-minute dose of happy nostalgia.
And it was a another 'd' which did it. A grand visitor fuelled by diesel which was making its first appearance on the region's railway tracks for - decades.
The 75-year-old Standard railcar, one of just six built to run the country's tracks, arrived to provide a series of return trips between Napier and Hastings and word had got around pretty quick - the tickets were soon sold out.
It first went into service in July 1939 on the Napier to Wairoa run and stayed on track through the 40s and 50s before being retired.
The front was the same as the back, so the driver would simply unbolt the required control from one cab after a journey and boltit in the other cab for the return trip.
As well as those who booked a 45-minute return trip on the Pahiatua Railway Society's railcar, a stream of people arrived at both stations to see it come and go - and along the way at every crossing people had their cameras out.
For Keith Smith of Hastings it was something he never thought he would see or experience again.
His last trip was in the late 50s.
During school holidays his mother, grandmother and a brother would all take the Standard railcar to Gisborne for a treat.
"We'd leave about 8 in the morning and finally get home again about 5.30 in the evening - we only spent an hour in Gisborne. We'd get something to eat, have a quick look around, go to the toilet then come back home again."
But he said the scenery and "really comfortable" ride made it all worthwhile.
"Crossing the Mohaka - now that really was something."
Mr Smith said when he heard it was coming to the Bay he was first in the queue. "I jumped at it - I never thought I'd see one again."
His mate Gary Lambert had never been on the Standard but had been on a few steam trains, which were his favourite. "They're marvellous - I love them."
He recalled how when it came to crossing the old Westshore embankment bridge the steamers would be shut down and be towed across as there was concern over the effect vibration of the working engine might have on the bridge.
Another passenger said it "brought the memories back in floods" and he summed it up: "I won't be able to wipe the smile off my face all day".
Art Deco Trust events manager Peter Mooney said the railcar had proven to be a huge success and he was already looking to have it booked in for next year's mid-winter DIY Art Deco Weekend.
"The whole weekend has gone really well," Mr Mooney said.
"We have had great weather, there's been a marvellous atmosphere about everything and of course everyone has had a lot of fun."
Most definitely a delightful, dandy Deco do.
