Meghan Markle [1] made her royal debut at the Wimbledon tennis championships on Saturday, when she joined her sister-in-law the Duchess of Cambridge to watch the men's semi finals, followed by the women's finals. The Duchess of Sussex had a good reason beyond her royal duties for choosing this particular match: her close friend Serena Williams was playing! To support her friend, Meghan chose a classic preppy look consisting of a blue and white striped shirt, and chic white trousers by Ralph Lauren.

This appearance marked the end of a very stylish week for Meghan. We don't think we've seen her in so many stunning outfits in such a short span of time! She began her week at Prince Louis's christening, wearing khaki Ralph Lauren [2]. Then came a serious fashion moment in a boat-neck Dior dress at the RAF 100th anniversary celebrations [3]. On her royal tour of Ireland, Meghan treated us to four outfits in 48 hours [4], ranging from a classic LBD [5] to a chic pantsuit [6]. Her final look of the week didn't disappoint, and she looked stunning as she cheered on her pal. Take a closer look for yourself ahead.
