It looks like you have done a great job on the jacket. I am sur eit will go over very well at your event.

As for fly plaids, I thought it had been commented on here, that you would rarely, if ever, find anyone in Scotland actually wearing one as often as us in North America do. I think they look really neat for extremely formal (wedding), but I also think they are very over the top and bordering costume status. Just my 2 bits.
