I agree completely with Paddy. I think it is not just a point but very important that you treat this as something very special that will be endowed with some great associations and feel doubly good to you over the weeks and years. Wear it around the house a little and maybe go out to the car to see about care during entry and exit. But this is something that should be seen as very special to the day of your wedding. Not the same thing your friends have seen you wearing about yet.
As to the technical aspects of owning this garment I have to say that Barb's book has been really informative and I feel comfortable and competent about kilt care from what I learned there and here on xmarks.
For the most part, save it for that special event.
Become informed and better able to make decisions about care.
Enjoy.
