This reminds me of the day of the dead, 'el Dia de los Muertos' celebrated by Mexican and Hispanic people, on the 1st of November, although the decoration on the face would probably be more colorful but their skin would often be pale and grayish. They are often depicted as brides with flowers in their hair. I've done a few illustrations like that so that interpretation immediately came to mind.
Very nice, Charlotte!
