Besides the fact that this is a gorgeous charcoal flannel suit, the scarf underneath seems to set off all the other details (fair isle, pocket square, belt, etc). In general, I think this is a good look if the scarf is worn as pictured. Swirling a scarf around one's neck looks extra feminine in my book. I have always thought the item was for pure decoration, and for a little warmth on the back of the neck. However, I highly reccomend silk when pairing with suits or sport coats. It will just feel better against your neck.
