A dress worn by Marilyn Monroe — probably not the first one that comes to mind — has just sold at auction for $4.81 million, a record for a dress.

The dress is the one Monroe wore when she famously sang “Happy birthday, Mr. President” to John F. Kennedy. While the dress is iconic in its own right, it may be the second one that comes to mind for many people when it comes to Monroe’s iconic outfits — after the white dress that famously blew upward as the actress stood over a subway grate in “The Seven Year Itch.”

The Kennedy birthday dress was purchased by Ripley’s Believe It Or Not Museum. The $4.81 million price surpasses the previous record for a dress sold at auction — the $4.6 million paid in 2011 for Monroe’s subway grate dress from “The Seven Year Itch.”

The U.K. publication The Telegraph says of the JFK dress: “One of the defining dresses of 20th century fashion, the sheer tulle design, scattered with tiny, glimmering crystals, was worn by Monroe on 19th May 1962 as she performed for President Kennedy ahead of his 40th birthday. It was an instant sensation and paved the way for ‘naked’ dresses, which still spark a furor when worn by the likes of Kim Kardashian and Beyonce today.”
