Whose wedding day is it?

Take a quick glance at this photo and you see a rather innocuous scene. Just a Wedding party right? A wedding party on the streets of Seattle, waiting to cross the street.

Look a little closer and you see a kilt. One lone (Scot?) in a kilt. Look even further and you notice that he's the only one of the wedding party wearing a kilt... while everyone else is wearing a suit. It stands to reason that it would seem that we have located the groom. It wasn't until you saw the bride, with the groom at her side did you realize that your assumption was wrong. I don't think I've ever seen someone who appears to be in the wedding party and yet sticks out more than the groom. Is he just being proud of his heritage, or just showing himself off? You be the judge.
