pincord/pinwale/needlecord: Corduroy’s wale count per inch can vary from 1.5 to 21, although the traditional standard falls somewhere between 10 and 12. Pincord is the finest cord around with a count that’s right at the upper end of the spectrum (above 16) and has a feel that’s as soft as velvet and superlight
