The capsule wardrobe idea — a small, coordinated set of clothes that all work together — is at least four decades old. It keeps coming back because the underlying problem never really goes away: most people own more clothing than they wear.

Stylists who have worked with clients for years tend to describe the same pattern. The first pass through a wardrobe usually removes 30 to 40 percent of what's there. The second pass, months later, removes another layer that turned out to be aspirational rather than actual.

What separates a capsule that lasts from one that quietly re-inflates is not the number of items. It is a small set of rules the wearer actually respects: a fixed colour palette, a limit on new purchases per season, and a clear place for everything to live.

Nobody has to own exactly 33 pieces. But most people benefit from owning noticeably fewer than they do now.
