You know, I like it. It has a modern look to it that would set you apart from other kilties. Unless they specificly say "black tie", I think it could pass for a formal occasion, at least here in the US. Some will disagree, but just being in a kilt upgrades your mode of dress.
The sporran I think looks OK. I think full mask sporrans are considered formal. Its not my particular style but thats why they make different styles, everyone doesn't have the same taste.
I hope the earthquake Sunday morning didn't disrupt your life too much.
