I have been to several weddings kilted. Usually I go with a nice shirt, argyle jacket, a solid tie, my best kilt, some matching hose and a regular pair of wingtips (brogues). I also have asked the brides if they minded me coming in a kilt. NEVER ANGER A BRIDE ON THEIR WEDDING DAY BY SPRINGING A KILT ON THEM. I think the belted plaid will be more of a distraction. You are there for the bride and groom after all, not to show off how Scottish you are. This isint meant to offend, just my personal opinion.
