Perhaps Kate's absolute favorite versatile jewelry is the pair of pearl drops that she's been wearing since the Summer of 2012. They are suspended on small diamond hoops and are understated enough to be worn with waterproofs on rough and tumble sailing engagements, as well as with a cocktail hat to a Buckingham Palace garden party. They are a staple of Kate's royal tours, she chose to wear them when she left hospital with Princess Charlotte, and she wore them this year with her first Gucci outfit to an engagement at the V&A Museum.
