So nice, she wore it twice! The Duchess of Cambridge stepped out with husband Prince William for an evening at Banqueting House in London in a familiar blue-green Jenny Packham gown.

William and Kate left their three children at home for the evening to attend the Tusk Awards. The Tusk organization supports successful conservation action in Africa including protecting wildlife and empowering communities to champion the fight against the illegal wildlife trade.

For this special evening, the duchess wore a recycled teal Jenny Packham gown that she wore previously in 2012 for a concert at Royal Albert Hall.

The stunning evening gown features a Swarovski beaded belt, cap sleeves and an intricate sheer lace back. The short sleeve dress also has a plunging neckline and a princess-y flowing chiffon skirt. The dress is a modified version of Jenny Packham’s ‘Aspen’ gown from the Spring 2012 collection. Kate accessorized both dress moments with a matching teal satin clutch with lace overlay.

For footwear, Kate wore Jimmy Choo Vamp high heeled sandals feature a high platform and glittering champagne straps.

For accessories, the duchess added the Queen’s diamond chandelier earrings.

And the duchess added her ‘Women of the First World War‘ poppy Brooch to complete the look.
