Born in Tehran, Iran, Bijan migrated to Los Angeles in 1973. His exclusive boutique on Rodeo Drive in Beverly Hills was established in 1976. It has been described as "the most expensive store in the world".
Bijan's main residence was in Beverly Hills, California, but he was also known to own residences in New York and Malibu, as well as Milan and Florence, Italy. Up until the time of his death, Bijan was one of few Iranians in the media limelight who were still permitted to enter Iran. Bijan was also known for his automobiles. Most notable in his car collection was a yellow Bentley Azure with black interior, as well as a Black Bentley Azure with yellow interior. He was also known to have a black Mercedes-Benz SLR McLaren with a customized paint scheme, a yellow Ferrari 430 Spider, a yellow Rolls Royce Drophead coupe, and a Bugatti Veyron, all of which he was known to park outside of his Rodeo Drive boutique.
In the late 1980s Bijan designed a golden Colt revolver. The gun had a leather handgrip fashioned for a .38-cal. Colt revolver inlaid in the cylinder was 56 grams of 24-karat gold, the gun was placed in a mink pouch in a Baccarat crystal case embossed with the customer's name. Bijan's own signature is engraved in gold on the barrel of the gun. Only 200 such guns were made. In 2005, one of these guns sold to Jacob Nahamia at Christie's auction house for over $50,000 USD. In 2000 Bijan courted controversy when an advertisement featuring a "rotund model named Bella" and himself was at first rejected by New York magazines before it was accepted by Tina Brown's Talk magazine.
Bijan dressed some of the world's most powerful men: President of the United States Barack Obama, former President of the United States George W. Bush, former Governor of California Arnold Schwarzenegger, American actor Tom Cruise, German TV host Thomas Gottschalk, British actor Sir Anthony Hopkins, President of Russia Vladimir Putin, U.S. Senator John Kerry, former Prime Minister of the United Kingdom Tony Blair, Michael Jordan, Paul Allen, Jay Leno, Giorgio Armani, Usher, the richest person alive Carlos Slim Helu, owner of several casinosSteve Wynn, designer Oscar de la Renta, Thomas Bodin, Tom Ford, Shahram Nazeri, Former Beverly Hills Mayor Jimmy Delshad, Footballer Saba Shakeri, U.S. President Ronald Reagan and Lerad Dumani have all been dressed by Bijan.
Bijan's fragrances for both men and women are known for their distinctive circular glass flacon with an open center and a dividing web. When half full, the fragrance fills two separate chambers, seemingly defying the law of gravity that liquid seeks its own level. One of these perfume bottles is featured in the permanent exhibit of the Smithsonian Institution. According to the 2001 Los Angeles Times Calendar Section, the Bijan Perfume and Fashion Business has brought in an estimated $4.2 billion in sales worldwide.
