Over the last decade, Kate Middleton has carried several bespoke Alexander McQueen box clutch bags. They’re often fairly similar in design: a rectangular box with curved edges on a contrasting metallic frame, finished with a jewelled clasp:
Black:


Red with a bow:


Dove Grey:


Black velvet:


Taupe Suede:


Some of the designs are variations on McQueen’s iconic ‘Skull Box Clutch’—all without the skull clasp! (Kate tends to have a jewelled/plain design on the closure instead, it’s more regal of course!)
