Catherine was seen wearing Alessandra Rich Pleated polka-dot silk crepe de chine midi dress in the portraits released by Clarence House to mark the 70th Birthday of Prince Charles. Inspired by Alfred Eisenstaedt’s 1945 photograph of a sailor kissing a stranger in Times Square for label’s Spring ’18 collection, capturing the essence of that iconic moment, this vintage-inspired dress is cut from polka-dot silk crepe de chine that falls to a pleated midi skirt. Highlight its retro feel with yellow sandals. The £1,225 dress is not available any more. But the Spanish label Zara has a fabulous replikate.
