Case in point? Supermodel sisters Gigi and Bella Hadid, who showed off their winning courtside looks during Wednesday night's match.

Gigi, for her part, was polished in breezy red pants by Simon Miller and a matching top that was backless and featured super thin spaghetti straps. A pair of white sneakers with black laces, round sunglasses, and a slicked-back bun rounded out her look.

On her feet, she wore brown sneakers with white tube socks. She accessorized with a white shoulder bag and tiny sunglasses, and pulled her hair away from her face with a '90s zigzag comb headband. Gigi and Bella were among several celebrity fans who cheered on Serena Williams as she faced off against Estonia's Anett Kontaveit at the Billie Jean King National Tennis Center last night. Other notable names in the crowd included Lala Anthony, Zendaya, Jared Leto, Tiger Woods, and Serena's older sister Venus.
