I seem to recall reading somewhere that silver/grey silk neckties are the most appropriate (traditional?) choice for a wedding. Can anyone add some details to this?

- Does it apply to any level of dress where one would wear a four-in-hand tie?
- Should the tie be solid or are patterns also common? If patterned, what types?
- Is there a reason for this guideline?
- Would this apply equally to the guests, as to the wedding party?
- Is this true for either a kilt or a suit?

Wedding season is upon us...
