Serena Williams seems to have forgotten to zip up her jacket before leaving her hotel.

The brazen US tennis star , 34, was court out as she enjoyed a stroll in Milan, Italy.

She was in town for a charity gala hosted by fellow champ Novak Djokovic, 29.

Last week the tennis ace showed of her super-toned figure as she relaxed on the beach on a well deserved holiday.

Showing off her toned figure, Serena looked amazing in the neon two piece as she jumped up on a wooden deck and let loose during the sun soaked vacation.

It follows a tough summer of tennis for Serena, who lost against Ukraine’s Elina Svitolina in the third round and also teamed with her sister in a losing effort to Czech stars Lucie Safarova and Barbora Stryvoca.

That loss ended their career record of 15-0 which dated by the 2000 Olympics, and followed it with a loss to Karolina Pliskova in the US Open semi final .

However, Serena has moved on from that disappointment with the launch of her Diamonds Unleashed collaboration during New York Fashion Week.
