Those old school stretch pants were pretty decent to ski in, they supported your muscles and looked surprisingly good if you were in decent shape. I had an expensive pair of nice ones and wore them for years, all kinds of weather, really very good performance for "old fashioned" fabrics and technology. Paired with some side zips you could handle anything.
Wool sweaters are pretty versatile too. Not in white but those Demetre padded ones weren't bad at all and you did get to feel like a bit Supermanish with extra arm muscles. It was the cotton turtlenecks we had underneath that sucked.
Dang I even miss the CB Sports pullovers and baseball jackets. Marker safety strap just under my knee to hold my tendons in place lol.
I know all the goofy neon one piece stuff didn't come until the 90s but here in the NorthEast, even at the peak of the 90s, I still bet the most popular colors were Navy Blue.

The whole pants-dragging urban jail culture applied to modern snow sports is an ironic joke... perpetrated on the parents who pay for that junk.
