It is a fascinating and fawning exhibition. At the King’s Gallery (until 18 October) some three hundred items of clothing belonging to Queen Elizabeth II are displayed – headless, limbless, fleshless – like the remains of extinct animals. Norman Hartnell supplies silky flamboyance and encrustations: lace re-embroidered with sequins and crystals. Hardy Amies, fresh from a ‘distinguished career as a spy’, offers a see-through mac and trim day dress praised for being figure-flattering but ‘demure’.
