Sharon Stone experienced a wardrobe malfunction Tuesday when she flashed some side-boob while at a party on fashion designer Robert Cavalli’s yacht.

The 55-year-old was in Cannes for the 2013 Film Festival and attended the party wearing a bold red gown that featured a large slit up her thigh, revealing even more skin as she partied away. However, she also revealed ample cleavage by way of showing off some side-boob.

The actress sported a blue beaded gown with a low neckline earlier in the day while she attended the Behind the Candelabra premiere at the festival, pairing it with a multi-strand emerald and diamond necklace. Stone completed the look with natural make-up and had her blonde hair hanging down her shoulders.

The film stars Stone's Basic Instinct co-star Michael Douglas as gay pianist Liberace. 

Joining Stone on the red carpet were Douglas and Matt Damon, who both take leading roles in Behind the Candelabra. Writer Scott Thorson, director Steven Soderbergh and producer Jerry Weintraub also joined Stone on the red carpet. 

Last year, the actress talked about how she got the role of murderous novelist Catherine Tramell in the film.

"My manager Chuck Binder actually broke into someone's office and stole the script," she said. "I read it and thought, oh my god, this is the greatest character I ever read."
