The nude embellished dress that Marilyn Monroe wore to sing Happy Birthday to John F. Kennedy is going up for auction.

The infamous Julien's Auctions is offering the dress on November 17, where they believe it will be sell for around $3m (€2.7m).

At the time Marilyn wore the dress, it was considered very daring (think Kate Moss' naked 90s get-up) and she even had to be sewn into it.

Ms Monroe passed away less than three months after her Happy Birthday performance, and President Kennedy died a year later.

The dress will be showcased at the Museum of Style Icons in Newbridge before it's November selling date.
