I agree, wearing a traditional kilt in Scotland is fine, but a contemporary kilt, that is even unusual in the States, will not get you the attention you would expect. I would head the advice of both Jock and Jordan, since they are both Scots living in different parts of Scotland.

I would think you would be better suited to wear a traditional kilt in a somewhat traditional manner, for a positive kilting experience. If you check out the threads of those who visited Scotland in the past year, you can get a few good examples of acceptable kilt wear in Scotland. Remember the kilt is Scotlands national dress, and while the contemporary fashions are starting to arrive in Scotland, it has yet to be embrassed by the Scots themselves.
