I remember it distinctly; Levi's was an official sponsor and designed three different outfits. One was a nice sports coat and slacks-or-skirt combination. One was a warm-up suit. I'm a little fuzzy on the third option, but I think it had more of a western flair. And there was a huge promotion, and ballots were set up in retail outlets that carried Levi's, so that the general public could vote on what the athletes would wear to the opening ceremony.
And the warm-up suits won. Which just goes to show what you get when you let the general public decide on anything.
