Angie, about Girbaud, I assumed they were French, but who knows, maybe it was just great marketing! They had their own shop in Chicago into the late 90s at least.
Also, shout-out to Esprit and their crazy colored corduroys. I recall having a pair of pink ones in a painter pant style, with a button fly, and wore them with a grey and pink fair isle sweater, and a different grey sweater that buttoned up the back.
By the way, that was another thing for me in the 80s. We reversed our cardigans so they buttoned up the back. That was a trick my mom taught me from the 50s!
