Kate was effortlessly chic throughout her 20s and beyond. From her college style to her wedding outfits, from her night-out looks when she lived in a London apartment to the clothes in which she attended her then-boyfriend Prince William’s polo matches, Kate got it right every time. Today, Kate’s the mother of three heirs to the throne—Prince George, Princess Charlotte and Prince Louis. Her passion projects include charity work concerned with addiction issues, mental health, art and early childhood development. In a recent speech addressing a project that will investigate the importance of the first years of childhood she said, “Only by working together can we bring about lasting change for the generations to come. Because I truly believe, big change starts small.” Click on the gallery to follow Princess Kate’s journey through the years!
