I, too, was a fashion disaster back in the late '70s, but for a totally different reason.
Up through college, my mother was still picking out my clothes for me. After that, I couldn't really afford to get new clothes, so I kept wearing what I had. I was so un-stylish that there were lesbians who wanted to take me shopping for a makeover.
No, really. That's the sort of think you cannot make up.
Fortunately, by the time I could afford to buy my own clothes, my sense of fashion had gone off in it's own direction. I tend to wear the same simple clothes year in year out, nothing pretentious, just classic lines.
Der Brucer, on the other hand, did succumb to the disco era clothing. He used to own several leisure suits, with the attendant shirts and shoes. He still had them when we met, although he wasn't so brave as to wear them any more. They were hanging in storage bags in the garage, on the chance that they might come back in style some day.
So far, we've been lucky and they haven't. We left them all in Long Beach when we moved, anyway. A good thing, too; if we'd brought them with us we'd have been arrested for crimes against nature in some of the states we drove through.
