According to a survey by online retailer socked.Co.Uk, 70 per cent of single women said that if their date turned up wearing odd socks, they would not see him again.
Some women surveyed said it showed a lack of effort, while others said they wanted someone who took pride in their looks, the Daily Mail reported.
Those who wear mismatched socks could be missing out when it comes to their careers, too.
Eight in ten bosses said they would think twice about promoting an employee who wore odd socks.
The survey also showed that half of men do not buy their own socks but rely on gifts from friends and family for Christmas and birthdays.
Replacing lost socks costs the average household in the UK 137 pounds a year.
