It was the 1970s and long dresses were IN.
I was so excited when Juno agreed that I could have a long dress! My friends told me about their frocks - various scarlets, electric blues (what can I say? It was the 70s) and even one in BLACK which was very, VERY daring for a 12 year-old.
I don't remember the actual buying of the frock. I might not even have been present because I can't imagine that I would have willingly selected what I wore to the dance that night.
Yes, it was a long dress. But it was BROWN. Very dark brown.
In the dimly lit Town Hall, I was like a little polyester short-haired turd.
