I have a vintage 1960's - 1970's Hippie carpet belt in a size M.  It is all shades of purple.  It measures about 34" in length x 1 1/2" in width (the brass buckle is about 2" in width x 3 1/4" in length).    The belt shows 2 or 3 area's where the carpet is worn off (very small) from wear I tried to show the worst in my photo's.
