I live in Madrid and honestly women carry designer bags everywhere and no one bats an eyelid - I take my Chanel when I visited different cities - Marbella, Gothenburg, Oslo, Copenhagen, Milan, Barcelona, London, Paris, Hamburg - no one bats an eyelid seriously in any of these. Seriously so many women carry designer bags. Of course if I go to well known pick pocket areas like las ramblas in barcelona I would turn the flap around as a precaution but that's it - you just have to keep your eyes open. I don't think it's unsafe to take a Chanel to Europe.
