Fashionistas would have us believe you can tell a lot about a person from the colour of their shirt.
But can you tell how much they earn, or how well educated they are...or whether they're likely to have a sneaky office romance?
A new study claims to have discovered that men who wear pink shirts earn an extra £1,000 a year, are better qualified, more confident and get a greater number of compliments from female colleagues than their more traditionally beshirted colleagues.
A poll of 1,500 male office workers claims to have also discovered that one in four men feels more attractive in a pink shirt, and those who often wear purple or lilac have the most office romances.
Those who prefer a simple blue shirt have the least.
Remarkably, the survey claims that men who wear pink shirts are twice as likely to have a Masters degree than those who prefer white shirts.
The survey conducted by Cotton USA also claims to have proven that those in the pink are the most green, with the pink-shirted among us being the most likely to have a low carbon footprint, with half taking public transport to work.
In interesting news for those looking to recruit, green shirt wearers are identified as the most likely to be late into the office, while those who favour white shirts most likely to be punctual.
Stephanie Thiers-Ratcliffe, International Marketing Manager for Cotton USA, said: 'You can tell a lot about someone by the colour they wear.
'Pink is a colour more men have been embracing recently and it's encouraging that they are not afraid to experiment with brighter colours.
'We spend most of our days at work and it's good for company standards, our own confidence and work ethic to remain smart, but that doesn't mean you have to be boring."
