Arriving at the event, the "Black Swan" actress wore a stunning mini printed wrap dress by French designer Claudie Pierlot. Due to Portman's dress being from the brand's spring/summer 2021 collection, it's no longer available to purchase, but the brand has released a similar wrap mini dress in cobalt blue.
In terms of accessories, she opted for a Christian Dior straw hat (currently sold out) that had the logo emblazoned on the front and a pair of oversized black cat-eye sunglasses by Ahlem with a chic green gradient. As for shoes, the petite actress gave herself some added height by opting for open-toe black espadrille sandals with a slim ankle strap. Finally, Portman was seen carrying the black Montaigne handbag, also from Dior. As mentioned earlier, Portman has been a Dior ambassador for a long time, so it makes sense that she owns a lot of the brand's coveted items.
Overall, her look is fresh, elegant, and perfect for watching tennis in. Portman's amazing sense of style strikes again!
