Redefining wars and fashion as we know them in the same sequence—— no one but a genius physicist can do that.
Oppenheimer changed the world in more ways than one. Along with the destructive weapon he brought to existence, his fashion statement was just as explosive. The movie brought back retro-styled suits and coat outfits and transformed menswear fashion.
The vintage aesthetic is again on the rise in the fashion world. This film is one of the instigators in bringing back old-fashioned trends. Sharp, crisp outlines and impeccable style are once again dominating the fashion scene.
Read on below to discover how Oppenheimer’s fashion style of the 1940s continues to inspire the modern world today.
From Academia to Nobel Award: Introduction to Oppenheimer
Oppenheimer is based on the biography The American Prometheus by Kai Bird and Martin J. Sherwin. The esteemed role of J. Robert Oppenheimer was played by the iconic Cillian Murphy. The movie explores the life of the theoretical physicist Oppenheimer from his early days as an academic at the Trinity Test to his contribution to the Manhattan Project.
The movie is a graphic biopic that explores themes of ethical dilemmas, political machinations, and personal struggles. It follows Oppenheimer in his journey of creating the world’s very first nuclear weapons. His discovery and the subsequent creation of nuclear-powered weapons changed the trajectory of this world as we know it.
The term “power” took on a completely different meaning thanks to this ordeal. Peace became even harder to achieve. The movie doesn’t just cover the concrete details of the case; it also explores the underlying themes. Still, also the internal struggle and personal wars fought in the journey of creating such destructive power.
The movie used IMAX technology to immerse the audience in Oppenheimer’s experiences. It also incorporates dual color palettes, with black and white sequences representing Lewis Strauss’s, played by Robert Downey Jr., perspective and color sequences representing Oppenheimer’s, adding depth to the narrative.
Oppenheimer’s Nuclear Impact on Fashion
Oppenheimer received acclaim for his detailed depiction of the advent of the first-ever nuclear weapons. The storyline and performances of some of Hollywood’s top stars truly elevated the movie to a grand level of status. The audience connected with the psychoanalysis of Dr. J. Robert Oppenheimer throughout the journey.
Outside of that, the impeccable dressing sense of all the characters also captured the viewers. To provide an accurate narration and storytelling of past events, a 1940s style was infused into the movie.
Oppenheimer’s posh and elegant attire piqued the audience’s interest in the fashion of the late 19th century. The crisp outlines and tailored silhouettes of the late 40s were revived and reintroduced in the fashion industry. The muted colors bring a serious and sophisticated look to the entire ensemble. Accessories like fedora hats and big, noticeable belt buckles add a vintage edge. The overall neat look was deeply appreciated by the audience as it served as a perfect narration device and elevated the entire experience.
Immaculate and clean dressing became the trend once more thanks to Oppenheimer. The story, along with Murphy’s acting and delivery, resonated with the audience, growing their fascination with the character and inspiring them to recreate him. Viewers recreate his iconic look with their own personalised edge, creating a whole new outfit.
Dress Classy Like Oppenheimer
Style Breakdown: How He Wore It
The most famous look served by Murphy in Oppenheimer’s role is the beige suit. It is a classy and impeccable look that represents the ordered and sleek style of the 1940s.
The suit blazer is made of suiting material, specifically cavalry twill, a durable and textured fabric. The Oppenheimer Coat features a viscose lining that provides comfort and allows for continued use. It also features a lapel-style collar characteristic of that time and a button closure that gives a sophisticated look to the entire ensemble.
In the film, Murphy styles the beige blazer over a light-colored collared shirt, which provides a subtle contrast. He also wore a dark colored tie and a shining silver belt buckle. The hat is a signature element, a wide-brimmed, fedora-style hat with a telescopic crown.
It’s described as having a pliability that allows it to be worn in different ways, reflecting the New Mexico environment and Oppenheimer’s own personality. The overall look is one of understated elegance, reflecting both his intellectual nature and the rugged environment of Los Alamos.
New American Jackets offers the whole suit as well as the blazer separately, so you can decide which look suits you better. Below are three styles that we believe would complement this iconic coat.
