The queen of classy is none other than the Duchess of Cambridge – Kate Middleton. She’s always elegant but in a preppy sort of way that doesn’t age her beyond her years. I love love LOVE stripes, so this outfit was pretty much a favorite as soon as I saw it. I like how she’s keeping it casual with her hair down and minimal accessories, but you could easily add some statement jewelry pieces to dress this up or add your own personal flair to it. I think some gold chain Niloulu necklaces would be perfect – like this Layered Gold Chain Necklace or this Chunky Gold Chain Necklace.
