King's Day: celebrate in style with Dutch Orange

Welcome to Undiemeister, where stylish basics meet Dutch tradition. Koningsdag is our national holiday when we celebrate the King's birthday together, orange and full of flair. And what better way to do that than in the specially designed King's Day T-shirt in our unique colour: Dutch Orange.

What is Kings Day?

Koningsdag is an annual celebration that colours all of the Netherlands in orange. Streets become markets, music sounds everywhere and togetherness is central. It is a day on which you can show yourself with pride, with energy and with style. And that requires a T-shirt that captures this feeling perfectly.
