First of all --Congratulations - - - Second, as you wish to be wedded kilted, are you presently a kilted man? Please, if you are planning on wearing a kilt, get it early and wear it. Learn how to sweep, sit and tuck.(Hamish video - use search) Practice getting up and sweeping the pleats into order. Practice wearing the sporran, belt and kilt pin. Practice aligning flashes and hose. If wearing a vest and jacket, practice moving around in them. Practice using the facility while kilted. You do not want surprises on "the day" dealing with sporran, aprons and needing to rush.
I dressed for my wedding in my clan tartan, kilted. My best man and company wore tuxes with my clan tartan as neckties and cummerbunds. My spouse was in Clan Lamont as were the rest of the company. The real fun of the occasion was the Minister kilted in Clan Campbell (her Clan) and the hosting group in Clan MacDonald kilts. I have been kilted since my early teens. My spouse at first was not keen on tartans, until the actual day when it all fit together. My your spouse to be and yourself enjoy the time spent on the planning as well as the future.
Unlike her wedding dress, the kilt is something that can have a busy future. Many previous posts have covered the Wedding Kilt. They have given you the names of three awesome custom hand stitch kiltmakers for the real Scottish wool that can be found on this site. I also highly recommend all three. For a P/V kilt Rocky (USA Kilts) is great. I do not know how soon the day is approaching, and that may limit your options, although I hope not for your sake.
All the best
