A button can fasten a garment, decorate its surface, suggest a memory or become a repeated graphic sign. Kelly used this ordinary component to make clothing conspicuous without relying only on expensive materials. The Met’s fall/winter 1988–89 ensemble record connects his approach to stories about his grandmother covering repaired clothing with multiple buttons. Treat that connection as an attributed biographical account, not a universal explanation for every embellishment.
The same record describes a velvet jacket fastened with flathead nails and paired with a toolbox purse. That example shows how the joke can extend from surface to function: hardware becomes fashion hardware. Ask what actually closes the garment, what merely resembles a fastening and how the accessory changes the reading of the ensemble.
The Met’s spring/summer 1989 suit lists cotton, rayon and plastic. Materials matter because an exuberant appearance does not tell you whether decoration is costly, handmade, detachable or structurally necessary. A visitor can enjoy the effect while still asking the object-level questions that separate design from a vague account of personality.
