A lot of minimalists like to have number limits on belongings.
Project 333, 100 things challenge, etc. I love these blogs and projects for motivating me, but honestly a number limit doesn't quite work for me. The milder versions have less constraints, but of course even the "you don't need more than 8 of anything" rule feels too restrictive.
Let me explain
I don't need more than 8 shirts..... ? Or is that no more than 8 long sleeved shirts? Or is that no more than 8 long sleeved button up shirts? Where do I draw the line at the classification of each thing? 8 pants? Or 8 jeans, plus 8 cords and 8 pairs of slacks? See the problem?
One thing is for sure, even with 8 of EVERY category, my fashionista sister would never understand any limit but the constraints of how much she can CRAM into her large closet and 3 dressers (and of course the off season closet and the formal wear wardrobe too).
My preference is a compromise. The limits are not numerical absolutes, and they aren't maximum capacity space constraints either... I figure if I can easily find what I need within the closet (or drawer)and everything in there is what I can wear NOW (the right size, and in good repair and a style I like) then that should be the perfect amount!
With this special density, the one-in-one-out rule is completely necessary. Otherwise things can very quickly slip into an over-crowded chaos.
Just ask my pantry... it is over the comfortable-access-capacity on a regular basis!
