Vintage Gold sunglasses - Brad Pitt - Once Upon A Time In Hollywood

Brad Pitt wears vintage gold sunglasses in Quentin Tarantino's Once Upon A Time In Hollywood (2019).

Leonardo DiCaprio wears the exact same pair of glasses. The brand and model of the sunglasses are not known.

The glasses are probably a vintage pair, provided by Old Focals, a company specializing in rare vintage eyewear for films and series. They also provided their own Old Focals Architect model for Al Pacino in the same film.

The model is a gold frame aviator style, so a good alternative would be the Ray-Ban RB3025 Aviator.

Once Upon A Time In Hollywood is the 9th film by Quentin Tarantino and starring Leonardo DiCaprio, Brad Pitt and Margot Robbie. Set in Los Angeles, the film tells the story of television actor Rick Dalton and his stunt double Cliff Booth as they try to get involved in the film industry.
