Throughout her long and controversial career, Madonna has never been shy about showing off her assets.
At the age of 54, however, she seems to have developed a sudden bout of modesty.
She protected her pale skin from the sun's rays in a long-sleeved white polo-neck top and three-quarter-length white trousers as she took a dip in the French Riviera.

Perhaps she chose the outfit - topped off with a colorful baseball cap - to fit in with the teachings of Kabbalah, the mystical religion she has followed since 1996.
Believers in Kabbalah, based on the teachings of Judaism, think white clothing teaches 'positive energy'.
By contrast, the stars' young boyfriend Brahim Zaibat, 24, went bare-chested and opted for more conventional beach shorts.

Meanwhile, her 15-year-old daughter Lourdes seemed determined to build up her tan in her white bikini.
The trio were seen frolicking in the water as they chatted and giggled while cooling themselves down.
Madonna is thought to be staying in a huge chateau ahead of her concert in Nice this evening

It will be the final date of her latest world tour, which has been notable for moments of outrage.
During a show in Istanbul, she flashed her right breast on stage. And days later, she exposed her bottom to an audience in Rome.
Madonna's holiday also comes after news broke that she is being sued for supporting Russian punk band Pussy Riot.

Three members of the punk band were sentenced on Friday to two years in prison for a protest outside Moscow's main cathedral against Vladimir Putin and his relationship with the Russian Orthodox Church.
Russian activists claim they were offended by her support for gay rights during the recent St. Petersburg concert, where there is a legal ban on promoting homosexuality to young people.
It was reported that Alexander Pochuyev, a lawyer representing the nine activists, had filed the suit on Friday, against Madonna, the organiser of her concert, and the hall where it was held, asking for damages totaling 333 million rubles, or nearly $10.5 million.

He told Russian agency, RIA Novosti: 'No one is burning anyone at the stake or carrying out an Inquisition. Modern civilization requires tolerance and respect for different values.'
The complaint includes a video taken at the concert showing Madonna stomping on an Orthodox cross and asking fans to raise their hands to show the pink armbands in support of gays and lesbians that were distributed among the audience.
