I only wear silk ties. I don’t like the look or feel of man made materials. That said the silk tie also holds a knot better than polyester. I wear a tie that suits my mood and the occasion. Mostly dark colored, and sometimes I buy two of the same and have my hatter convert one to a matching hat band.
BTW>>>my great grandfather was a tie manufacturer, he set my grandfather (his SIL) up in the shirt business. When I was young we sold both lines in my father’s clothing stores. This was known as vertical integration. The government stopped oil companies and movie studios from doing this, but not the garment industry.
