I've always heard you should dress down when traveling as to not be a target for being robbed, so I wonder how people think about this?
I guess that depends where in the world you are going.... Paris, Rome, Tokyo, Dubai etc you're probably fine where as if its Lagos, Harare, NYC, etc you'd probably be better being more careful.
Handbags, purses, wallets, carry on I think generally is fine given its with your person all the time. I am never sure about the LV monogram suitcases for the hold etc, to much of a risk of that one being the one that accidently got dropped and burst open whilst its out of everyone's sight.
