I have 100s of the narrow ones, too. I find some quite sophisticated....a solid color with one small object (like a cherry) on it. Some have that 1950s 'atomic age' edge to them (a small atom icon or similar). I wore one to my job interview and got the job (I don't think it was because of the tie, though). Oh heck, I like all neckties made before 1965.
In my much younger days when I owned exclusively fat belly warmers I received a skinny solid red '50s tie with a so-called 'atomic age' icon (some kind of planet with an orbiting ring) as a Christmas gift. At the time, this was way too 'modern' for me. Over time, I've loosened up...Although I still go fat most of the time, a skinny tie every month or two is good for a change of pace.
