Ok the trousers have now turned up. I think they'll be fine though had thoughts they might have been a little better in a dark khaki. Can't wait to get the final pieces to see how it all looks together.
As long as you leave the tips orange, I don't think there would be any problems. I've never been to a con but on all the videos and pictures etc non are orange or yellow or blue! So I think if you just use some common sense and only put them in your holster when you are inside the expo then you should be okay . I'm sticking mine in my quiver while I walk across the road from the hotel .
