It’s Saturday morning and you’re window shopping before late brunch. As you hop from boutique to boutique with no real intent to make a purchase, you see it. There it is, glimmering in an imaginary celestial spotlight: the perfect staple piece. It’s from a brand you know and love, and you can picture yourself wearing it a dozen different ways over the next decade. You know you’re going to buy it as soon as it slips over your shoulders in the dressing room, and you mentally start making space in your closet.
