The 'Girls Trip' actress wore an eye-catching multicoloured gown with a plunging neckline by Prabal Gurung and she explained she'd asked the designer to use crimson, azure, yellow and green on the hand-plisséd chiffon dress because they are the colours of the flag of Eritrea, the home country of her dad.
She told 'Entertainment Tonight': "It's the only one that exists. 'Cause I asked him to make a dress that represents Eritrea, my father's country, so these are the same colours as the flag from Eritrea."
And the 38-year-old actress admitted the bright garment reminded her of a parachute.
She added: "Doesn't it remind you of, like, candy or a parachute in first grade? Hot Dog on a Stick, maybe?"
It isn't the first time Tiffany has paid tribute to her dad on the red carpet.
At the Oscars earlier this year, she wore a traditional Eritrean gown in his honour because of something he'd said to her several years ago.
She explained at the time: "My father is from Eritrea, and he passed away last year. And he said, one day I would end up here, and if I ever end up at the Oscars to honour my people, so I'm honouring my fellow Eritreans."
But that wasn't the only outfit the 'Keanu' star wore at the Academy Awards as while on the stage, she wore an Alexander McQueen dress that she'd previously donned for the 'Girls Trip' premiere and hosting 'Saturday Night Live', as well as another gown.
She said: "That was amazing. Rocking my $4,000 Alexander McQueen dress again. Wearing this Brandon Maxwell dress. Feeling cute because he made [it] for me.
"Rocking my Eritrean princess dress for my father in the beginning of the evening. That was amazing."
