We have a vintage nos 66" piece of "exquisitely dainty lace elastic" which was made for Waist Bands on Panties and Half Slips.  It is 63% nylon 25% cotton and 12% rubber.  It is 5/8" wide and still has it's stretch.  There is some light tan discoloration which I have not tried to remove from this on parts of it.  It may or may not wash out with stain remover.....  I will ship internationally, please contact me with your country for a shipping quote.
