Last but not least: Study reveals which pick-up line really brings success

This is the advice if the man does not know the nationality of the woman. But of course the same applies here: other countries, other customs. If a woman is from Germany or Canada, the man should praise her skin. If she is Italian, French or American, he should praise her clothes. If she is British or Turkish, he should praise her legs. If she is Spanish or South American, he should praise her hair, and if she is Dutch or Portuguese, he should praise her ears. The most frequently used phrase, regardless of the woman's nationality, is "You have beautiful eyes", but the phrase "You have beautiful lips" has the highest response rate worldwide.
