The tennis star wore an A-line skirt, black sneakers for comfort, and a black minidress with sheer elbow-length sleeves to flaunt her toned legs. Her makeup looked natural with a neutral red lip, and her long, highlighted hair was done in loose waves.

She was holding 14-month-old Adira, who was wearing a white T-shirt with long sleeves, denim shorts, and adorable white high-top sneakers.
