Gold Nylor sunglasses - Brad Pitt - Allied
The glasses have a gold frame and black arm ends. These vintage glasses frames can still be found regularly on eBay.
Similar current pairs of sunglasses are the Ray-Ban Olympian, but that model has rims around the lenses, while Pitt's sunglasses have a semi-rim frame.
Similar but not the same: Ray-Ban Olympian.
Another similar pair of sunglasses is the vintage model Persol 2123-S (see photo here).
In the same film, Marion Cotillard wears a pair of LGR Alexandria sunglasses.
Thanks to Quentin for the ID
