I'm going through a "purple tie" phase, apparently. I recently realised how versatile purple can be, but - alas - I only have one cheap purple tie (that I bought just to give the color a chance) and now I'm looking for something a little bit more fancy. I'm kind of hesitating between grenadine (grossa?) and shantung.
I appreciate Mr. Hober's comments on durability and the risk of unlined ties loosing their shape, and I will take them into account, but in fact my collection of ties is so large (given my limited needs, as I oftentimes work from home) that my most worn ties get perhaps 10-15 days of wear per year, so durability is not my no. 1 concern.
