The Duchess of Cambridge showed off her toned physique to the best effect Friday, baring her back in a super sexy dress!
The future Queen of England, 30, wore a $4,620 Jenny Packham Aspen gown with a plunging neckline and an even racier lace back.
The royal couple attended a black tie gala at the Royal Albert Hall to mark the final countdown to the 2012 London Olympic Games.
The designer, whom Kate often wears, described the fashion icon’s look, saying “The style combines an emerald lace bodice embellished with Swarovski crystals and a pleated skirt, ribbon waisted with a crystal and flower embellishment and matching bespoke clutch bag.”
