I'm looking for a blended or linen tie for a suit. More specifically, I want a tie that is either non-silk or at most 50% silk (can't wear pure silk for religious reasons). I want something that is formal for an evening event. Wool ties often look informal or better for daytime events. Cashmere or wool/silk blends tend to work well. I've looked at department stores and major brands, but I find mostly silk ties. See the pics below of the suit. It is blue, but lighter than navy . Appreciate any ideas!
