A thinking-out-loud, work-in-progress thing.
My life’s item should be in a single printable A4 size Paper at a readable font-size and perhaps even blocks of boxes to not try to cramp in too much item. Create a layered modular capsule wardrobe, and stay within a monochrome color, without or as minimal display of logos, no-frills and no-brand.
Stay dark; the highest color would be like dark navy blue and cream on the lightest end of the palette.
