On the other hand, wearing the same thing everyday does save time and brain effort. I wear the same thing everyday and have done so for about two years. Technically my shirts are different, but I have narrowed down my options considerably. I own five pairs of the same pants(outlier; black). I have twelve button up shirts in plain colors (four are white, four are blue, two are grey, two are green). I either wear a NAU blazer or a black light jacket. I have three of the same sneakers and one pair of dress of shoes.
Everyday I wake up grab a pair of pants and a shirt. Depending on the weather, I can grab a jacket or not.
I consider it a type of lifehack. I do not think it is for everyone. It really simplified that part of my life.
