I recently bought ~30 pairs of the same underwear which I prefer. I definitely see locking down a set of favourite items for the basics of your daily wardrobe, and then buying those items in bulk, as a big efficiency boost if you have more important things to do with your mind than worry about the what you're going to wear each day. Makes sense to focus on basic items: socks, undies, t-shirts, pants, jerseys. Then you don't have to worry about needing to do laundry all the time, running out of items you prefer, choosing between different models, choosing when you go shopping again. Ultimately you would want to extend this beyond clothes: food, household items etc. and automate it as much as possible, so you don't even have to worry about re-buying - your system is set up to order replacements on schedule as required. Edit: just realised I'm in the process of doing basically the same thing with discovering and standardising my favourite haircut.
