Kate Middleton's bright white shorts with gold buttons are the perfect vacation style staple

Kate Middleton' stepped out in a stunning nautical outfit yesterday and we're lusting after her stylish summer shorts from Holland Cooper.

• Duchess Catherine's nautical ensemble consisted of a navy striped top, with loose, white shorts perfect for summer days, as well as her signature Superga trainers. 
• The Duchess paired her look with a bouncy blow dry and natural makeup.
• In other royal news, what football team does Prince William support and why is he President of the FA?

The Duchess of Cambridge enjoyed an adventurous day out, where she took part in sailing activities and met with sailing teams from both the UK and New Zealand. The Duchess is a royal patron of the 1851 Trust, which aims to help young people explore science and technology through sport. During her visit to Plymouth, she met with young people to discuss sustainability, had a go at practical eco tasks and even took part in a Commonwealth Friendly Race.

The Duchess looked as flawless as usual in a more relaxed outfit choice with some on-trend bright white shorts from Holland Cooper. It is thought the gold buttons could have been custom-made for the Duchess.

"The high-waisted design provides a flattering silhouette that perfectly complements the female form, making it a must-have when composing a relaxed, yet sophisticated aesthetic."

Catherine's look was a big departure from the glamorous Kate Middleton dresses we're used to seeing on the Duchess. But you might recognize shorts as a staple in Catherine's wardrobe - the Duchess wore shorts during her and Prince William’s royal Caribbean tour of The Bahamas in March this year, but they were a shorter grey pair.
