I'm planning on outfitting the entire wedding party in Leatherneck kilts from SWK, and other than my best man and one groomsman (and myself of course) none of them are Marines.

They will be wearing those kilts in honor of MY day though, and I know they all have respect for me and the Marine Corps, and I dont ever expect any of them to ever represent themselves as Marines when they arent.

To me it is no different than a bumper sticker or a T-shirt. When done with pride and integrity it can only be a positive thing.
