Perry popped out of a sports car with rapper Riff Raff onto the red carpet just before the televised awards began. She called her tight, studded patchwork dress a custom Versace in a “throwback to Britney and Justin”, a la the American Music Awards 13 years ago.
“This is how we do the remix,” Perry joked.
Amber, who is married to Wiz Khalifa, went for a Vegas showgirl moment, her chest barely covered with loose loops down to a tiny bikini bottom. The look evoked McGowan oh-so-many years ago.
Ariana Grande upped her sex appeal with an ooh-la-la black leather mini and matching thigh-high boots, but kept the signature girly high ponytail. British pop singer Charli XCX wore a yellow tiger-print leotard.
The 21-year-old Grande worked long zippers back and front on her strapless Moschino moto look. Charli’s tight leotard and leggings were designed by the same Italian brand.
Designer Jeremy Scott joined Charli in her yellow, yellow world in bright tuxedo tails — chest bared — with a big smiley face on the back.
“I feel sexy in it,” said Charli, among the early red carpet walkers. “I think my spirit animal is probably a tiger.”
Kesha, sometimes a red carpet shocker, went classic in a floor-length sparkler in a far more subdued carpet than VMAs of yore.
Taylor Swift arrived in a long-sleeve, blue lace shorty romper with a lettered alphabet theme to go with her new short ’do. It was designed by London-based Mary Katrantzou.
Orange is the new Black star Laverne Cox was in sparkly blue, a space-age one-sleeve from Marc Bouwer, and Miley Cyrus tugged on a tiny strapless black leather midriff-baring top she wore with high-waisted matching trousers. “Marc has been so good to me,” said Cox.
Jessie J stood out in a pale green vintage Halston goddess gown with a deep V halter, and Jennifer Lopez showed off her curves in silver cutouts.
