The KonMari method, as Kondo has coined her system, is simple: keep the belongings that “spark joy,” and get rid of those that don’t. That overpriced cocktail dress you always feel guilty for never wearing? Gone. Those sad laundry-day tights with the holey toes and stretched-out waistband? Sayonara. The system leaves precious little room for excuses: no maybe-I’ll-wear-it-somedays or but-I-got-it-as-a-gifts or I’ll-just-wear-it-to-beds.
