From the Knicks playoff run and championship win to the World Cup and now the US Open, it truly has been the summer of sports. And, in custom spray-painted Knicks merch, vintage soccer jerseys, and preppy tennis-inspired looks, our fashion has been reflective of that. Tennis and fashion have a long, influential relationship. With polo shirts, pleated skirts, and white sneakers being a product of the sport, players becoming fashion icons, and notable designers collaborating with the athletes on bold looks, it’s clear that the relationship is still going strong.

At the US Open yesterday, I couldn't help but observe attendees' looks with appreciation. Some committed to a preppy or sporty theme while others simply took it as an opportunity to wear their favorite kitten heels and jeans. Now, we’re taking a look at our favorite looks on the court and from our favorite VIP guests.

Ahead, the best US Open looks, both on and off the court.
