Amy Pond - After Sherlock, my mind goes to the Eleventh Doctor's spunky companion when I think of scarves. Incidentally, I usually wear my scarf in the same style (well, I've been doing that since before there was an Amy Pond).
Mat Cauthon - Just like most of the characters in the Wheel of Time series, Mat's been through a lot. He was hanged and nearly died, but the plus side of the unfortunate mishap is that he ended up wearing a scarf to hide the scars. Well, I guess the other plus is that he just nearly died.

The Fourth Doctor - Not many men could wear a scarf like this and even fewer would be able to make their name stand apart from it. Tom Baker managed just fine.
Stephen Maturin - The steadfast companion of Captain Jack Aubrey, Dr. Maturin was practical in almost every way. In the movie interpretation of the character (Master and Commander: The Far Side of the World), he sported a neck wrap constantly. Also, Paul Bettany.
Every Student At Hogwarts - Students at the magical school have a long, cozy-looking scarf as part of their uniforms. Adults seem to wear them a lot, too. Muggles could stand to learn from this example.
Last but so very far from least, Sherlock Holmes. I do not apologize if this gif mesmerizes you to the point of distraction. (via The Carnival of The Random).
