How long do you take to decide what to wear each morning? Less time than it takes to make a cup of tea? Five minutes? 10?
Marks & Spencer questioned 2,000 men and women to ask that very question, and discovered that women spend, on average, 17 minutes deciding what to wear each day. That works out at six months over a working lifetime, or a whopping four whole days a year.
But you can stop being smug if you come from the other side of the gender divide - the same survey revealed that men take an average of 13 minutes in the morning agonising over the same decision.
Fashion journalist Simon Glazin admitted to being taken by surprise by the similar time spent by both sexes in choosing their outfit.
"It depends on what you do for a living and how extensive your wardrobe is," he told Julia Hartley-Brewer. "But I kind of get the fact women take 17 minutes.
“There’s a whole double standard. People don’t like to see women wearing the same thing twice, but it’s OK for a man to wear the same navy suit for 13 years.
"What's more surprising [to me] is that men take 13 minutes.
"Expressing yourself with what you wear is becoming more important [for men]," he added. "I think now more than ever with menswear, it's a massive growing market in the fashion industry.
"Men are getting more fashionable and wanting different things. They are spending more money, and more time getting ready.
"This survey puts that in concrete."
