OK, I'll be the weird one here and say, if you are going to embrace the uniform, then store the rest. To me the appeal of a uniform is being appropriately dressed for your daily activities without having to think about outfits or what goes with what. You put your focus on other aspects of your life.
I did something like this when I travelled for six weeks with a black skirt, black pants, and a few tops (same style but in black, grey and white). It felt oddly liberating to not have to think very much about my clothes for the duration. The other odd part was that it was the one time when I always felt quite appropriately dressed whether I was climbing over ruins, riding a bike, dining at a restaurant, or going to the theatre. Strange, but true.
