The Duchess of Cambridge, Kate Middleton, visited the National Maritime Museum today making her first solo appearance in weeks. She wore a white and navy shift dress by the brand Jaeger -- very summery and nautical. It's also extremely fitting for the day, as she was meeting sailors!

The dress is a new piece for Kate, and sold out extremely quickly this morning (but don't worry, they have a lot of other great dresses that are definitely Duchess-worthy).

Kate was in attendance for the launch of the British challenger team for the 35th America's Cup. She spoke about her love of sailing, and more than likely reminisced about that time she beat William on the high seas twice during their race in New Zealand! According to reporter Victoria Murphy of the Mirror, the Duchess "was in her element" today.
