Billboard Music Awards 2017: Cher's revealing outfits will remind you of her '70s style [PHOTOS]

Remember when Cher wore a sheer feathered jumpsuit in 1974 during the Met Gala? Well, she almost brought back her '70s fashion style at the Billboard Music Awards 2017. The singer, who was honoured with the ICON Award on Sunday night, wore revealing outfits that reminded fans of her '70s and '80s fashion style.

The 71-year-old singer delivered a memorable performance on her '90s anthem Believe and her hit song, If I Could Turn Back Time, that was released in 1989. She started her performance with Believe and wore an outfit that left little to imagination. It consisted of thin silver chains dangling over a crystal bra. Cher used pink heart pasties to cover her nipples. She wore a blonde wig with pink-dyed ends and a lipstick shade that matched her dyed hair colour.

"I don't like getting old," she had told Billboard earlier. "I'm shocked that I can still run across the stage at my age. I thought I'd be dead!"

Cher attended the Billboard Music Awards 2017 on Sunday at T-Mobile Arena in Las Vegas to accept the ICON award and to perform on BBMA stage after a gap of 15 years.
