The Fourth Doctor's scarf is iconic and there is a reason it is cosplayed so often. Not only is the scarf stylish, it also was the first recognizable costume piece from Doctor Who. Jon Pertwee started this a bit with having a recognizable clothing style but he at least changed the costume as episodes went on. The Fourth Doctor is rarely ever seen without his scarf. Today, one of the few Classic Who designs you will find on merchandise racks is, of course, the scarf. It's possible to find the scarf itself, but there are also long socks, carpets, and t-shirts featuring the coveted design. The Fourth Doctor's been helping fans to dress to impress since 1974.
