Need to accessorize but don't know where to start

[Kilted Jeeper]

I am new to the kilted world and right now only have one. I have a Sportkilt in the Ferguson tartan which I am very pleased with. I would like to start wearing my kilt to some more formal events including but not limited to Masonic events (Drumlin Sq. Lodge #1180 in NY) , holiday parties, etc.

Previously I only have worn my kilt in a very casual fashion, typically with combat boots or Teva's and a t-shirt. I want to put an outfit together correctly but have a limited budget in which to try and piece something suitable together. I have no immediate deadlines to get this completed but I would like to at least start putting together some quality pieces and frankly I have no idea where I should start. Do I need a PC jacket or will a typical sportcoat be OK? Any advice for the newbie would be appreciated.
