Why is Marilyn Monroe such a huge icon?

She was beautiful and had loved to have fun. At that time most women, even actresses dressed and acted like they were running for sainthood. Marilyn loved to drink and she always dressed in something that revealed that great figure of hers. I've seen and read interviews of people who worked with her and she was hard to work with. It has been over 40 years since she died and she has never been forgotten. The people who are popular today won't be able to say that.
