1960s- 70s groovy double knit pants

1960s / 1970s double knit groovy trouser pants. Has no tags except for the double knit and how to wash it and wrinkle free. A super cool pant with very unique designs the pants. I think they can be unisex. they have a high rise and acquire no belt with double button type setup at the waist. tried to find some like it on the internet and I can't. I used to be able to wear them when I was a size 30. They're very form fitting.
