That's great that you lived there! Were you there on exchange? And I love languages, though I'm afraid of the French language. The R pronunciation is really hard for me, so I stay away from it.
But I love Italian and I'm learning a little Arabic and Maltese.
Sorry to assume you didn't know those things, I don't know many people here well.
I don't know about khaki specifically, but what I meant was that Europeans generally dress up on a daily basis much more than North Americans. At least the French and Italians definitely dress up more; you would know much better about the Germans.
