Also among the most loved fashion items of the past were leather biker jackets, dungarees and band t-shirts.
The research, which was commissioned to mark the launch of the new Samsung AirDresser, which also revealed how a number of these memorable trends are still considered wardrobe staples – with one in four saying skinny jeans are one of their fashion must-haves.
A quarter of women favour an LBD, and one in 10 adults have a leather biker jacket.
As a result, two-fifths feel today’s fashion is mostly made up of old styles and trends which are making a comeback.
A spokesperson, said: “Our study just goes to show that there are many memorable trends from over the years, and as a result people are hanging on to items they perceive to be classics, while also investing in vintage finds.
“This is great for sustainable fashion but often these clothes need to be cared for properly to protect them for the future.
“This is one of the reasons we have developed the Samsung AirDresser, to redefine how people care for their clothes and help prolong every garment’s lifespan.”
The study also found plain t-shirts and a pair of trainers are among the wardrobe staples for the nation, as well as black jeans and plain black trousers.
But one in 10 would say a designer coat to keep them warm in the colder months is the most important item in their wardrobe.
Nearly half (48 per cent) see these items as essentials because they ‘go with everything’, while 64 per cent said they are just so comfortable.
And 49 per cent enjoy wearing them because they are a good fit.
It also emerged that just 11 per cent of those polled would describe their fashion sense as ‘on trend’, with as many as six in 10 describing their style as ‘comfortable’.
More than a third would say their look is more ‘basic’, while 13 per cent think they have a ‘vintage’ edge.
