What are the elements of Dutch national culture? How to apply in the clothing design in a unique way?

When I was small, I drank a bottle of powdered milk, and the woman in white and blue traditional Dutch clothing on the bottle, carrying an iron bucket in her hand, loaded with milk that seemed to be overflowing with fragrance, behind which were green pastures and a group of fat cows. When I was a little older, in a favorite clothing brand store, I encountered the season's clothing fashion pictorials shot in Amsterdam, the strong ethnic flavor, and the fusion of Dutch national elements in the design, which aroused my longing and desire for Dutch culture. It turns out that besides milk, windmills and tulips, there is another fantasy world in Holland. The upcoming graduation design is the best gift to commemorate the end of college life, and I always feel that I want to give it a different meaning from my previous works, so I would like to give it a little bit different meaning, and Holland is my destiny as well as my muse. I have never set foot in this country, and I still have little understanding of Dutch culture, especially the traditional national culture. Then take this platform, devoutly ask all kinds of gods, pointing out the magic.
