I am that type-A friend. I have a spreadsheet for everything and don’t go anywhere without a to-do list, so when I discovered I could use a data-led approach to declutter my closet using an app, I dove straight in.
The concept is simple, albeit a bit time-consuming overall. You use a wardrobe app (several versions are available on app stores) to document all your clothing pieces, and then tag them whenever you wear them.
