Acceptable attire?

[Ryan Ross]

And here I always thought the glengarry had a more military look than the balmoral--just what kind of bonnet would be considered a "civilian" style?

I think part of the problem is that male hat wearing, in a formal context, has become quite uncommon, of late. That said, perhaps a balmoral with no dicing would be considered a bit less "military" (though that's already what ardchoille's wearing)? I really have no idea.
