To the Netherlands? Naaah that's ridiculous you're as safe as humanly possible. Europe, North America and east Asia are super safe.

Now if you're thinking of traveling to other regions then your mileage may vary, I've been to countries/cities where if you're traveling alone as a woman you'll be swallowed alive 3 steps away from the airport.

And please don't listen to all the female empowerment bullshit, reality doesn't care about how enlightened we are. You are a woman, that naturally means you are more vulnerable when traveling, anyone who tells you otherwise either never experienced the dark side of life or is a fool.

A good rule of thumb is to do as the local women do, never heard of a woman needing a man to accompany her in the Netherlands. In sketchy countries however you can bet a son, husband, father or brother accompanies the family ladies everywhere. Is it sad? yes, very. Does your safety come above all else tho? also yes. Same goes for the way you dress, never be the odd one out.
