Are you wearing the black kilt because you can't find one in Lindsay, or is the black a preference to a tartan kilt? With some investigation here on the forum, there might be someone who could loan you a Lindsay kilt for the wedding. I'm not a big fan of all-black kilts, but I think in this case, with the fly plaid and flashes (both), it could look really nice.
Please post lots of pics, and include one of the cake, too.
