I too am a keeper of accounts and lists, hence the way I organise my clothing, by seasons and complete outfits with regular reviews and shopping lists. I do not however have a separate clothing expenditure spreadsheet, that is subsumed into the personal expenditure column of one of the several spreadsheets I use to run the family finances.
I could tell you, but do not intend to, how much in total I have spent on all aspects of personal discretionary spending, including clothes, for each of the past 20 years. Like you Grannytwice, friends and family who know I have all these spread sheets think it hilarious, but generally I do not tell them, to avoid their mirth.
