Which outfit is "more Scottish?"

[Bugbear]

I would think the more "Scottish" outfit would be jeans, a jumper, and a pair of trainers.

I would also say keep it simple.

That's the ticket.

* Edit *
I wear flat caps, but not because I think it is part of Scottish attire; more that it is a hat style that I like, and has a flavor of the early nineteen-hundreds America.
And I am responding to this post in part:

Nobody wears flat caps over here any more, the odd teenager and golfers but other than that it is strictly the 60+ brigade who refuse to go out without a 3 piece suit and a flat hat
