It was the same in the 1950's, we had the Teddy Boys, then the mods and rockers, then the mini skirts not forgetting the shoulder pads. A certain fashion doesn't last long but seems to always make a comeback many years down the line. Let them have fun and enjoy the way they dress, they are not harming anyone. I am now 81 years old and wish I had kept all my clothing from ther 50's ad 60's, just to look at them as they would have brought back so many memories, even though I can close my eyes and still see them in my minds eye.
