A Look Back at Britney Spears's Most Memorable Onstage Outfits

Only Spears can perform a mega eight-minute mash-up of all of her greatest hits in bejeweled lingerie and over-the-knee boots. 

Spears guest-starred during Rihanna's set at the 2011 Billboard Music Awards, complementing BadgalRiRi's racy white bodysuit with a black bondage version (with bunny ears and hand cuffs, because why not) for "S&M."

Spears paid homage to Madonna's bridal style for a rendition of "Like a Virgin," along with Christina Aguilera, which ultimately led to the infamous three-way kiss that went down in history as one of the most outrageous moments in MTV VMA history.

Spears assumed the role of referee and took the job seriously with an inspired black-and-white striped crop top and black pants, eventually stripping down (with the help of jersey-clad backup dancers) to itty-bitty booty shorts during "I'm a Slave 4 U."

Spears gave her racy abs-baring, booty-baring looks a break, opting for a rather demure ruffled number for one of her sweetest hits: "I'm Not a Girl, Not Yet a Woman."

Arguably one of Spears's most iconic outfits. While the average human would have recoiled back in fear, Spears completed her set and belted out "I'm a Slave 4 U" with nothing but a cut-out bralet, bejeweled booty shorts, and a python. 

Remember when Britney and JT twinned it up in denim? She went from that iconic look on the red carpet to another one onstage—a crazy fringed top and high-shine silver pants.

Michael Jackson and Britney Spears? When you have two pop icons sharing one stage, what you get is a monumental moment in music history. Of course the only outfit worthy of that is a sheer glittery, flouncy number that refracted light at every angle.

The halftime show ended on Aerosmith's turf, where Spears and then-bae JT (along with his boy band N'Sync), Nelly, Mary J. Blige, and Tremors & The Earthquake Horns all performed "Walk This Way." 

Cover your eyes! The Princess of Pop caused quite a stir when she performed her hit single "Oops...I Did It Again" (which also received three nominations), tearing off her conservative black suit to provocatively reveal nude second-skin separates.

There were dancing robots and lightning orbs, but all of that faded into the background when Spears appeared in a cut-out red-hot jumpsuit (that perhaps foreshadowed her red latex one-piece in her "Oops... I Did It Again" music video released later that year) during "Baby One More Time."

As the rule-breaking student, Spears wore a midriff-baring glittery leather two-piece that would have been grounds for detention during her performance of "Baby One More Time."
