Vintage Patterned Thigh High Stockings 1960s-70s O/S Black & White

Cool vintage thigh-high stockings, in a black and white horizontal stripe pattern. You will need a garter belt to hold these up. They do have some stretch and the reinforced toe makes them seem older, but the fabric seems more like a polyester knit. They are somewhat heavy and in good wearable condition, though have been used. There aren't any holes or stains, maybe slightly faded towards the foot area.No brand.
