Unless you're going to be doing something sporty, dress up a little.
Flip-flops, shorts or scruffy clothes in general tend not to make a good impression in fashion-conscious Europe. In France, a man may be late but don't take it personally – French men are notoriously bad timekeepers.
But the rule almost everywhere else in Europe is: don't.
In most countries, the man may offer to pay the bill but he wouldn't automatically be offended if the woman suggested splitting the bill, or paying for the drinks or some other aspect of the ‘date', such as cinema or theatre tickets.
In the US and other English-speaking countries, the kiss just doesn't have the same significance it does elsewhere.
For example, in the UK, a woman might kiss one or more men when she's out in a club or bar (or vice versa) but it wouldn't necessarily mean anything or lead to a relationship of any kind.
So what you say may be taken at face value – and you shouldn't always take to heart what's said to you. In the UK, drinking a vast amount of alcohol can be central in beginning a sexual relationship with someone.In most European countries, rather than going on specific ‘dates' as you might in the US, getting to know someone romantically is far more casual: "Walks in the afternoon/evening which may be followed by an informal drink at a café or a bite to eat at lunchtime", or "meeting up in a group with friends" is not uncommon, says some European expats.In the Netherlands you might take a walk or go on a bike ride.If a man keeps calling you, don't start thinking he's a bit of a stalker.In France and Spain it's not unusual for a man to call/text/email a lot – it just means he's interested.
In France, Germany and Belgium, it's common for the man to ask a woman out, but in Switzerland, the men can be a little reserved so women might want to give them a nudge.
