The classic video branded Madonna with a her "Material Girl" nickname, a track that is so quintessential 80s.
Inspired by Madonna's fascination with Marilyn Monroe, this video is an homage to Marilyn singing "Diamonds are a Girl's Best Friend" from the movie Gentlemen prefer Blondes.
The first part of the video shows illustrates the assumption that guys think women are all materialistic and will want lavish and expensive gifts, thinking they can buy her love.
But in reality, as the end of the video demonstrates, the real way to her heart is as simple as a bouquet of flowers and a realistic happy love with guys who are down to earth.
The irony was often lost and/or ignored by journalists, so the name and the image stuck.
