I have a few questions about pinned collars, regarding which I have been unable to find any information in previous threads. Is there a standard, classic tie pin? What kind of collar is best with a tie pin? Is it better to get the shirts that have the pre-made holes or not? Are there occasions in which it is not appropriate to wear a tie pin? If so, what are they? Any recommendations on where to buy a tie pin, and the appropriate price range? I would appreciate any feedback.
