Roberto Cavalli Just Cavalli 1973 Black Gray Jeans

The orange hue you see on some pics is just the light. There is no orange. Bought it back in the 90s in some boutique here in NYC but never ended up actually wearing them. They say 1973 on the label but I don't know what that's about. Bought them for around $500-$600. They widen at the ankles almost like bell bottoms. Unisex.
