Jock,

I have several dress sporrans that I'd be happy to loan to you. I can ship to your destination address if you'll cover shipping there and back.

I have a sealskin sporran that I wear here in the US, but I wouldn't tempt fate by going through customs with it.

I agree with Piperdbh, though. American weddings that I've attended don't seem to follow the strict rules of etiquette (12noon is more formal, guests to weddings which occur after 6pm should wear tuxedos, etc.). I would contact the family of the bride and ask what they expect male guests to wear. You can then plan your highland attire so as to be the equivalent.

Cordially,

David
