The math nobody does
Cost per wear is a simple division that almost nobody performs. A coat at two hundred, worn a hundred times, costs two a wear. A dress at eighty, worn once, costs eighty. The expensive coat is cheap. The affordable dress is dear.
The wardrobe's ledger does not match the receipts. Multiply the dress by every unworn piece in the closet and the real number arrives. The wardrobe you own is the most expensive clothing you have, and the least used.
