It's an exercise in fashion frugality. Try taking any six items from your closet and for 31 days, wear only those six items
"I liked the idea of a challenge, so I just took it on, really. It didn't really take all that much persuading. Although I have to be honest, there was a lot of skepticism from people that know me about how well I'd actually stick to it," said Kirsty Saddler.
Saddler, along with 100 or so other men and women across the globe who call themselves "Sixers" took on the challenge.
"Some people wanted to see how creative they could be with stuff. Anti-consumption was our biggest group. And then what we call curiosity-masochism which a lot of the guys fall into where they're just like, 'I wonder if I could do it,'" said Heidi Hackermer co-founder of Sixitemsorless.com.
"I've had people come to me on week three saying, 'Are you doing that?' And I work with them and I sit next to them every day! And I'm like, I've worn the same outfit four days in a row," explained Hackermer.
Without a closet full of clothes to choose from, Saddler started focusing on other ways to spice up her outfits.
"Lots of broaches and belts and things like that came in to play, where I normally wouldn't make the effort. So the funny thing was, getting dressed in the morning actually felt much quicker," Saddler described.
Only a few days into her experiment, Saddler found she was less frazzled in the morning and more eager to come up with different ways to mix and match her items," she added.
"You're taking away one element of stress in your life - what am I going to wear? That makes your life more simple and therefore less stressful," explained Marcus Buckingham, author of "Find Your Strongest Life: What the Happiest, Most Successful Women Do Differently."
But of course, there were a few challenges.
"During those 31 days, I traveled, I worked, I went to parties, I went for a weekend away, you know I had important meetings. The temperature soared, and I did not resort to Febreze, I would just like to say," Saddler said.
Not all those 100 people made it to the fashion finish line, but for Saddler, it was another lesson learned.
"I learned I over think what I wear and why I wear it. I learned that actually I often mindlessly buy things," Saddler said.
Saddler said she actually missed wearing only her six essential pieces, but she was excited about being able to wear color again.
