These flashy pants are 1970s through and through; right down to the tiny burn shown in a picture (ash from a joint) and the safety pin used to clasp the waist. Otherwise, the pants are in good shape as shown in the many pictures. Size 11/12 was smaller in the 70's. The waistline is about 13 inches across. The inseam is about 33 inches long... just right for the colorful, clunky platform shoes that were worn with the pants but are long gone. I believe the material is a polycotten blend. Please enlarge the pictures and ask questions if you have any. Thanks for looking!
