We have a small-ish walk in closet off our bathroom, mostly my stuff though shared with my husband. I have dozens of pairs of shoes (most in this closet, sneakers and boots and garden shoes split between the coat closet and garage). The less used and out of season shoes are in big boxes and bins on closet floor. The main in-use ones are in a vertical fabric hanging shoe holder. Only a few pair are in original boxes.
When I was working, I had to put “overflow” out of season clothing elsewhere (originally hung in a portable closet in the unfinished basement, then in son’s old closet once he went to college; now a few formal dresses are in daughter’s old closet).
