The Duchess of Cambridge, née Kate Middleton, loves to debut new looks while on tour, and in her practical way she then folds these novel pieces into her wardrobe. The down-to-earth beauty resurfaced a stunning dress for an official engagement on Wednesday (Aug. 24), which keen fans were quick to recognize.

The 34-year-old stepped out in London sporting a white-and-blue LK Bennett poppy dress that she first wore in 2014 during her tour of Australia and New Zealand.

She finished off the look with the trusty nude heels that she often champions, a coordinated clutch bag and sapphire blue diamond earrings.

Kate was returning to her royal duties after nearly a month away from the public eye and was accompanied by her husband, Prince William.

After the royal wore the LK Bennett dress in 2014, it transpired that comedian Mindy Khaling had sported the dress just the week before.
