Marilyn Monroe was a famous American movie actress from the 1950s and early 1960s. Her life is being detailed in a new movie on Netflix, Blonde. It stars Ana de Armas as Marilyn Monroe. Monroe was well-known for her costumes in the movies. She wore a bright pink long dress to sing the song Diamonds Are a Girl's Best Friend. And most famously, she wore a white dress that blew up as she walked over the subway in the movie The Seven Year Itch. The costumes have been talked about in popular culture. They have been recreated and reimagined many times in Hollywood movies and even in low-cost clothing shops. In 2011, the famous white dress that Monroe wore was bought for $4.6 million. And a copy of the dress went for $120,000 several years later. That explains why Jennifer Johnson felt a lot of pressure to get the costumes just right for the movie Blonde. As costume designer for the movie, Johnson was not able to study Monroe’s costumes in person. Johnson and her team watched films, looked at photos, and used information from a book by William Travilla who was responsible for Monroe’s famous looks. Even though the team could not use the same materials to make the costumes for Blonde, Johnson said it was important that the structure of the dresses was similar, so that they would not look like low-priced copies.
