Princesses Lights Festival

Ariel, Anna, Rapunzel and Aurora: four characters, and only one of them comes from Frozen, whatever the tag on this page says.

The occasion is a festival of lights, which in practice means evening dress. Long gowns, hair worn up or elaborately down, and accessories picked to catch light rather than to add colour. Pale fabrics and metallics read better against a night scene than dark ones do, and the wardrobe has been stocked with that in mind.
