If you love dancing and going out and mingling, then you will love the idea of having a 1970s fashion party where you can disco the night away. Have all of your guests come in clothing from the 1970s complete with psychedelic dresses and and shirts to big hair dos and flared pants.
Bring out that disco ball, put on a white suit and you could be the John Travolta of the evening. The music from the 1970s is great to dance to and all of your friends will have a blast dancing the night away. If you are stuck for where to find 1970s clothing, then second hand stores is a great place to start. They are inexpensive and you can find some real gems.
