15. The Knit Tie — If the silk tie was all the rage this summer, the knit version's the on-trend solution for fall and beyond. Pair it up with a casual oxford for the professorial thing, or add some luxe texture to your suit look for a conversation starter. And, go ahead, even mix it with a stripe or patterned shirt for cool contrasting.
