I'll be travelling to Amsterdam the end of this week and am not sure what season to dress for. I checked the temperature forecasts, but that didn't help much. Don't want to have to drag around a jacket all day although I don't want to get caught freezing in the evenings either. Anyone have any advice on how warm or cool it usually is this time of year and what you'd advise to take? Also, I see it's supposed to be pretty casual. Would jeans do to go clubbing in the evening?
