The Duchess has an extremely gorgeous collection of evening dresses. Among them is this beautiful Temperley London Amoret Black Lace Gown that she debuted in January 2012 at the London premiere of War Horse. She again wore this gown on a few occasions.
The $2,520 gown was described as,” a timelessly elegant choice for the evening” with the demure sleeve length and gently scalloped finish. It featured Scalloped and eyelash-trimmed plunge front, cuffs and hem, hook-fastening black silk removable belt, keyhole back, detachable blush silk slip to line with concealed button fastening at the back”.
