I have been looking down these posts and just wanted to make note that J. Higgins makes their 8 yard kilts from wool imported from Scotland. (Not sure if you wanted a plaid or something else) I have currently just bought 13 oz Robertson Hunting and they are great. Your first post notes that you are looking for a formal kilt which made me think of these guys first. I don't know if the other companies offer wool, but I have bought poly kilts from sport kilt and from stillwater. The poly kilts are just fine for casual wear but just do not look as sharp as the wool (my opinion). The sport kilt has better velcro than the still water and a few other features which are nice. If you can sew or have someone who can the Stillwater kilts are just fine. I buy them for my sons and then sew down the pleats some on the back this makes them look better. The poly kilts also tend to 'pill' with use and this makes them look worn before their time. This can be rectified with a disposable razor (to carefully shave off the pills), some starch and an iron. This will make them look new again! I have not purchased an 8 yard from any other company than j. higgins probably never will.

One more note: I learned a little trick for those of us who are a little round when I have bought kilt belts they have had two loops on them. If you put your sporran chains through the loops on the belt and slide them forward you can adjust your sporran to hang under the buckle and not under the belly. It looks nicer. (tip I got from a Scottish vendor in Payson, UT. Bless him )

Good luck with your kilt. I am sure you will look grand!
