From RS Feb 1974:

I was alive in the 1970s. A bit too young to wear these things, and let's just say I'm happy I was because nothing here is to my taste, no matter how well it may be made. I don't know what it is, there's something very boring and corporate about these clothes. It's late 60s, not 70s, but if you gave me Catherine Deneuve's character's fancy wardrobe in
Belle de Jour I would not wear it. That's how ugly I find those clothes.
I hate the whole era, the colors in particular. I hate the greeny yellows, the yellowy greens, the oranges.

Movies and TV programs set in that period always are awash in that palette.
I also hate the 1950s, so I'm running out of recent decades to emulate.
