I commented a few years ago saying I generally felt safe in European capital cities wearing some jewelry if it wasn’t flashy enough. Not sure if things have gotten worse in actuality but I’ve heard more stories of friends/family being robbed on vacation since so now would be a little more cautious. A friend had a designer backpack stolen out of their car when thieves followed them from Barcelona to a gas station rest stop and broke into their car while one family member was still in the car (luckily my friend had taken the kids inside briefly so kids missed that chaos). That really made me feel unsafe, like the boldness and lengths they went through beyond a casual petty pickpocketing thing. :/ The local police told them car break in scams/distractions like that were getting more common.
