Why is this portrait so popular? Because it depicts an adorable child dressed in her Sunday best? As was the custom of the day, the young girl is portrayed as a small adult lady. That she is playing a role is betrayed only by her facial expression. Unfortunately, we know nothing about her identity or her family. Perhaps she resided in Haarlem, like the portraitist Verspronck.

　　《穿蓝衣女孩肖像》是荷兰画家Johannes Cornelisz. Verspronck的画作，现藏于荷兰国立博物馆。该画作将一个可爱的小女孩描绘成一位small adult lady（小妇人），而我们对她的身份或她的家庭都一无所知，也许她和肖像画家Johannes Cornelisz. Verspronck一样居住在哈勒姆。
