If you're looking for the classic skinny/slim tie, one that maintains a thickness of 1.5" all around, this is the tie to get.

I concede to the complaints of most of the reviewers here - the material isn't anything great, but this tie is exactly what I was looking for. The thin shape means you can wear it out for relaxed yet formal business or you can wear it out for pleasure. It works great either way, and it's a nice dark black.
