Check the weather forecast just before come over and wear the same as you would at home with given weather.
Wear what you want.
>>We dutch men prefer short skirts and high heels though.<
I always though there was something strange with you Ger. Each to their own though ;-:
Wear whatever you want. We get all kinds of tourists here, from dreadlocked tattood youngsters to motor gang types, from Japanese funky hipsters to fancy business people, from Chinese mass groups to Americans in shorts with big white socks pulled all the way up. Nobody will take much notice of what you wear, even if you come in drag. This is Amsterdam!
As for the weather: it could be anything from +5 degrees to +35 degrees centigrade, and anything from summer hailstorms to gray rainy days or a heat wave. Bring thin layers to combine. If it's very rainy, just buy a cheap foldable umbrella or rain poncho at HEMA or another shop.
Haha, Ron, I meant the women on high heels of course.
I tried but they didn't have my size...
I am sure you can find them if you try, Gro.
I understand there is quite high demand for large-size women's shoes in Amsterdam.
Ger, I think I have the answer to your problem:
It's rather disturbing that you guys want to see me in heels that desperately.... ;)
