Miley Cyrus has no problem showing skin, so it was only a matter of time before the 20-year-old showed us the full monty.

The “We Can’t Stop” singer posed naked for a new T-shirt from designer Marc Jacobs’ “Protect the Skin You’re In” campaign, which hit shelves today. Sales of the $35 cotton shirt — available at nine Marc Jacobs boutiques around the country — benefit the NYU Cancer Institute and NYU Langone Medical Center. Earlier today, Cyrus tweeted a photo of the design along with the message; “Check out my @MarcJacobsIntl #ProtectTheSkinYoureIn tee❤❤❤We gonna save alot of lives #marcfam.”

This is the first time she’s dared to go completely bare, but Cyrus has previously exhibited a fondness for going pantsless on the red carpet, at magazine and video shoots, and even in her everyday life. Click on to see Miley’s best naked-from-the-waist-down fashion moments.

One of Cyrus’s earliest experiments with the pantsless look happened at the 2012 Billboard Music Awards, where she walked the red carpet in a Jean Paul Gaultier blazer and Christian Louboutin heels.

With the help of stylist Simone Harouche, Cyrus put together a number of bottomless ensembles for her “We Can’t Stop” music video, which was released earlier this summer.

In May, stylist Carlyne Cerf shared a behind-the-scenes photo of Cyrus in pink American Apparel briefs, a skull-print biker jacket and matching boots by Jeremy Scott on Instagram.

Cyrus’ pink underwear appeared once again in V magazine’s 2013 summer issue, which featured a risqué fashion spread titled The Emancipation of Miley.

Cyrus covered up on top and from the knees down, but apparently forgot to put on pants when she performed on Jimmy Kimmel Live in June. “I did not realize when you walked out you were wearing your underpants,” Kimmel quipped.

During a stop in Chicago to promote her new single, Cyrus tweeted a racy selfie that showed her in a Chicago White Socks jersey and heels. Later that day, she tweeted a picture the look from the back.

When Cyrus traveled to Canada to visit on-again-off-again fiancé Liam Hemsworth, she posed for a fan photo in a vintage Tupac shirt, camouflage vest, and shower shoes.
