Blac Chyna's Mom Tokyo Toni Rips Her Grammy Awards Dress

Blac Chyna‘s mom is NOT a fan of the way her daughter dressed for the Grammy Awards … ripping her child’s fashion choice as “horrendous.”

Tokyo Toni tells TMZ … Chyna’s outfit, an all black one-piece body suit decked out in rhinestones and feathers, was a “horrible” look — and she’s seriously questioning her daughter’s decision.

For Tokyo, the Grammys are all about looking elegant … and she would have rather seen Blac Chyna bust out a blonde wig and a golden dress and call it a day.

Of course, Blac Chyna’s dress is getting tons of attention … but her mom thinks it’s for all the wrong reasons.

Tokyo’s also taking shots at Chyna’s new boyfriend, Twin Hector … she thinks the rapper seriously influenced her daughter’s Grammys look, which she also dragged as “terrible.”
