Suits are too formal for the office and most people would prefer to wear jeans.
That's according to a survey of 3,000 adults where two out of three of those questioned said they believed it was fine to wear jeans, while three quarters described a suit and tie as too formal.
Even bankers agreed, although in smaller numbers, according to the study by workplace firm Regus.
Chief executive Richard Morris said: "Everything about the world of work is changing, from where we work to the hours we spend working to what we wear.
"This more relaxed attitude to workwear is a reflection of the fact that the office environment is now a lot less formal in many cases - lifestyle and work are integrating.
"Business leaders are learning fast about measuring on results rather than attendance and presentation. If a job's done well, who cares if it's achieved in flip-flops?"
But there's still one item of clothing seen as a no-no.
Tracksuits were the least popular item of clothing, according to the survey, although many employees in media and marketing firms see nothing wrong with wearing sports clothes to the office.
