Sitting on a sunny terrace in Amsterdam, I suddenly had to think of late Martin Bril. He's my favorite writer and invented rokjesdag.
Skirts days is that one day in spring all women (like magic) suddenly wear skirts, bare legs underneath. A dress is also possible, but no panties to the legs. That is deception.
Yesterday & today were typical skirts days in the Netherlands. A tribute to the creator of skirts days.
