Minding your manners, avoiding emotional Facebook rants and knowing what cutlery to use are the modern day signs of class, according to new research.
Saying 'please' and 'thank you' is the cornerstone of class according to a survey of 2,000 Brits, followed by reading widely and having good table manners.
Avoiding text speak, being bilingual and maintaining great posture also made the top 50 touches of class.
For women, subtle make-up, never drinking from a bottle and displaying cleavage sparingly were signs of holding yourself well.
While for men having a firm handshake, knowing when to admit you're wrong and owning a tailored suit made the cut.
A spokesperson from European fashion brand Peter Hahn, who commissioned the study, said: "Projecting the essence of class successfully requires a number of factors to work harmoniously, from your dress sense to your manners to your skillset.
"It helps if you have read your way through a bookcase of classics or can speak a couple of languages, but if your skirt is too short, your bow tie too sloppy or your posture too lax, your classy persona can falter."
Also in the top 50 were being able to handle your drink and knowing poetry that doesn't just begin and end with 'I Wandered Lonely as a Cloud' from William Wordsworth's 'Daffodils'.
Placing a napkin on your lap when eating and not wearing football strips as casual wear also featured.
For women, smelling nice, confidence and sensible heels are sure-fire signs of classy couture.
While for men, crisp white shirts, holding the door open for others and taking pride in their appearance are all ingredients that go into making gents suave.
Age is also a factor in levels of class. Brits believe the optimum age for classiness is 45 and that men and women generally get better with age, though men more so.
Dignified decorum on social media is a must for a quarter of Brits, while a fifth thinks wine knowledge is a sign of sophistication.
Despite these simple rules of class and etiquette, 86 per cent of Brits believe that people lack class nowadays.
In fact, an honest 36 per cent happily admit to having no class, with just one in 10 Brits confident in their classy credentials.
Nearly three quarters of those surveyed think that a touch of class is an important trait, but also believe that the manners, behaviour and fashion sense necessary are dying out in modern times.
When it comes to classy celebs, the Royal Family are considered beacons of style and substance, with Kate Middleton, Prince William and Prince Harry securing top spots in the countdown.
Taylor Swift, Emma Watson and Idris Elba are also considered some of the classiest public figures around.
As for the decade with the most charm and swagger, the 1950s come out on top followed by the decadent 1920s.
By comparison, just one per cent of those surveyed chose our current decade as the classiest of the last hundred years.
The Peter Hahn spokesperson added: "We're all accustomed to the adage 'sex sells', but actually leaving something to the imagination can be much more alluring than the shortest skirts or an overt cleavage.
"At Peter Hahn we know that a well cut garment will achieve the perfect silhouette, which is far more likely to get you noticed for all the right reasons."
