"Van der Waaij was fascinated by the timeless look of the Amsterdam citizen orphan girls. He made a series of paintings and drawings of models dressed in the red and black costume of the citizen orphans. His paintings idealized the appearance of the orphans, who seem to be shrouded in some transcendent charm: some sort of charm seem to emanate from these girls, which probably had nothing to do with the realities in the orphanage." http://vangoyourself.com/paintings/amsterdam-orphan-girls/
