Generally, looking as though you could be in the band and not just with the band is a great way to get a backstage pass. The musician is your style icon, look to 60's bands for your inspiration like the Rolling Stones who were not afraid to be free and experiment with their clothes. Their groupies were hot property just look at Marianne Faithfull, who in my opinion was so fucking cool, the original groupie who also happened to win the heart of Mick Jagger!
So all you budding groupies out there grab a leather biker jacket or an afghan coat, some platform shoes, sunglasses, and remember these are a MUST! Take hold of your heart Rock stars and groupies = heartbreak, but hey think of all the fun you will have, you can smoke legal and illegal cigarettes in places where a smoking ban has been in place for years, and you can wear a blanket instead of a coat and no one will judge you because your group is so fucking cool.
Go make your future, Groupie...
