From Beyoncé's Bodysuit to Spider-Iggy: All the VMAs Onstage Fashion

Taylor swapped her romper for a silver fringed two-piece for her performance of "Shake It Off."

The Aussie and Brit stars slipped into black and silver spiderweb catsuits for their performance.

Nicki's first look for "Anaconda" was a sparkling green two-piece with matching body art.

A quick wardrobe change (too quick, perhaps?) and Nicki donned a revealing black dress that had to be held together.

Ariana hit the stage in a space-age silver outfit with thigh-high boots and structured hip detail.

Another quick change, and Ariana sported an even tinier leotard in black and white with a new pair of boots.

To join Ariana and Nicki on stage, Jessie wore a long-sleeved mini with waist-high slits.
