J. Robert Oppenheimer (played by Cillian Murphy) is the titular protagonist at the heart of Christopher Nolan's film Oppenheimer. The primary physicist responsible for the creation of the atomic bomb, Oppenheimer's life included no shortage of drama including an affair with Jean Tatlock during his marriage to Kitty, and many inquiries into his political affiliations and ideologies.  The Manhattan Project of which Oppenheimer was a part took place in the 1940s, so your costume should evoke a vintage silhouette as much as possible.  Oppenheimer wears several different suits throughout the movie, often favoring grey and brown shades.  He also owns a rather unique belt buckle that is silver with turquoise.  To recreate his look from the film, choose a brown or tan suit, with a matching tie, shoes, and flat-brimmed hat.  Add a belt with a fancy buckle, a pipe, and a wedding ring.  Lastly, you can recreate his round identification badge by writing "K-6" on a plain white button.
