A study of 2,000 women, commissioned by UK uniform supplier Simon Jersey, finds the average woman spends more than an hour per week—for a total of three days each year, or five months over a woman's working life from age 18 to 65—choosing what to wear.

It breaks down to about 12 minutes every workday morning, 10 minutes every weekend morning, and about 27.5 minutes before a night out. You think that's bad? Half of women also worry about their outfit the night before or before getting out of bed in the morning.

Even with all that planning, two-thirds of women admit to trying on multiple outfits before leaving the house; about 15% have regretted their choice and returned to pick something else.

It's no surprise, then, that about 25% say they've arrived late to work because of deliberating what to wear. What's to consider, exactly? Well, 37% of women who say choosing an outfit is stressful cite concerns about whether their choice is suitable for work.

Other worries relate to the dress code, weather, looks, and whether it's flattering. Simon Jersey concludes uniforms could save time and stress; its survey doesn't explore how long men stand in front of the closet, but KIRO 7 has a theory: "They probably take just as long as women do. Maybe Simon Jersey doesn't have as many male uniforms to sell."
