Vintage black wide leg trousers with pleats

These are my pants which I purchased in Hong Kong in the 80’s. This style is trending now and these are super cool. They are made from a sort of lightweight crepe material. The front has pleats with the zipper in the back. The legs are wide and straight. They are a vintage size 8 but in Todays sizes it’s more like a 0/2. Please check the measurements provided in the photos.
