You probably did but, did you file a report to the police about the things that were stolen? If so did you have the serial numbers from the other things. Mabye it will lead you in the right direction if they find one or two pieces. Why steal a suit? It's not like you can just sell it easily or wear it without someone knowing who it belongs to.
In this costuming vein all you have to do is to post a pic of something and 20 people will chime in as to who made it, when and where. (and who owned it last!)
I hate people that take things like that. It isn't even for the sake of losing money out of it. It is the fact that some things can't be replaced. I could tell you stories about that.
What part of the country do you live in... Lair members local to you might be able to keep an ear to the ground locally in their own circles as well, if they are local to you. I think a suit that nice WILL turn up somewhere.
Well I posted up the pic Cary, on the UKfanfilms forum, we get a good few members of the UK501st over there too so there's more peepers on it now. Least this way if some fecker tries to sell it you'll have peepers on both sides of the pond scanning for it
