More than 7 in 10 workers say what they wear in the office has changed in the last 10 years.
Research from Savills Ireland shows 40% of people feel we've become more casual.
"If you look at the tech sector, that trend of casual work attire probably started 20+ years ago in Ireland and then other sectors started to follow suit," Savills Spokesperson Andrew Smyth said.
Almost 90% of men still own a suit though, compared to more than half of women who don't.
25% of people say the office style is more varied.
So, do you think we've become too casual?
