With a uniform wardrobe you have several identical items that you wear, like a uniform, and just change into fresh ones each day.
It is followed by several high-profile people, such as Mark Zuckerberg and the late Steve Jobs.
The idea is supposed to be that it frees up your mind from making small decisions, so that you can instead concentrate on the big ones.
Intrigued, I followed it for a year.
However, I found that the small number of seconds it takes each day to choose clothes outweigh the boredom and monotony of wearing the same thing every day.
Daniel Radcliffe famously used a uniform wardrobe while starring in a play and wore identical outfits every day to and from the theatre. His reasoning was that pictures of him wearing the same clothes would be worthless, as no one could tell when they were taken.
Unless you are using a uniform wardrobe to defend against the paparazzi, it’s not something I would recommend.
