She donned the two-piece again in June 2014 while visiting Bletchley Park.

Middleton's appearance on Friday was a way to help inspire young children to get involved in sailing and the marine industry. According to a post by the Kensington Palace via Instagram, the 1851 Trust's educational workshops "help students engage with the science, technology, engineering and math's of @Landroverbar's challenges."

The Duchess was all smiles as she chatted with the aspiring sailors.

At one point, Middleton even joined competitive sailor Ainslie and the Land Rover Bar Team for a sailing training session. Judging by her facial expressions, it seems like she had an absolute blast at sea!
