Meghan Markle [1], the Duchess of Sussex, is back in the US to support her BFF Serena Williams [2], and she looks darling in denim. The duchess kept things casual as she attended Saturday's match and opted for a button-down J.Crew dress [3] (£132) with a grey J.Crew jumper [4] and Victoria Beckham [5] aviator sunglasses.

Based on her past stylish picks, we know Meghan is a fan of denim although she doesn't publicly wear many pairs of blue jeans as a royal. More often, we see her in denim dresses [6] which give her wardrobe an all-American feel. She's also a frequent J.Crew shopper, with many of her shoes, clutches [7], and coats [8] coming from the brand.

Ahead, see even more glimpses of her look and bonus points if you can guess what she and Anna Wintour are talking about. Fingers crossed it has something to do with next year's Met Gala — hey, we can dream, right?
