Will-o’-the-Wisp

(Here are very similar descriptions for a woman’s version and a girl’s version of the same outfit. The electric stars would have been very modern and fashionable, less than a decade after the invention of the light bulb.)

Women:
Flowing hair falling over black fashionably-made evening dress; tiny lantern carried in hand; star of electric light in the centre of the forehead.

Girls:
Black lantern in hand, hair flowing; black tulle dress with iridescent beads; star over the forehead of electric light.
