If youre going to have a Jedi Wedding, you cant just walk up to the altar in a wedding dress or a morning suit. If youve gone this far, you may as well go the whole hog. Dont force it on your guests because that would make you a complete and total Jar Jar (Im determined for that to catch on as an insult) but the bride, groom, best man and other members of the wedding party should wear appropriate clothing. The bride and groom should naturally be in Jedi Robes (as should whoever is conducting the service) and potentially have your ushers dressed as Clone Troopers or Imperial Guards. Though this is likely to make them never speak to you again so bring up the subject tactfully. And if youve got more money than sense, see about bribing your chauffer to dress up as a Rebel Pilot. But if you get a horse and carriage, dont dress the horse up as a Bantha because, to be perfectly honest, we've had more than enough of horses masquerading as other animals in the past few months.
