On Tuesday, the film premiered in Berlin and the Oscar-winning actor opted to wear a brown skirt showing off his multiple tattoos, including one of a rhinoceros and another that depicts a skull.
The 58-year-old actor also wore a matching brown jacket, an unruly pink shirt, black combat boots, and a pair of sunglasses to complete the look.
In 2004, Pitt also said that men wearing skirts would become a trend while promoting his movie "Troy."
He told British Vogue: "Men will be wearing skirts by next summer. That's my prediction and proclamation. The film answers to both genders. We were going for realism and Greeks wore skirts all the time then."
In the movie, about the Greek epic poem "The Iliad," Pitt had to wear a leather skirt which he said, in an interview with The Sun in 2020, was "chafing" him while filming.
"You get older, you get crankier, and comfort becomes more important. I think it's as simple as that," he said. "I don't want to look ostentatious, but if you come close, you notice. I like how the lining feels. It's those details that are important to me. It's too exhausting to follow trends."
"Bullet Train" is in theaters on August 5.
