This was Aru's outfit for the Masquerade ball:
You see Arulisse.
She appears to be a Half-Sylvan.
She is average height and appears to have come of age. She has subtly slanted, faintly crimson-haloed, bright heather blue eyes and soft, immaculate alabaster skin. She has layered, silky obsidian-hued hair loosely styled with some silver filigree hair beads scattered throughout. She has a delicate face, a straight nose and a narrow waist.
She is in good shape.
She is holding a pleated glossy silk bag secured with a silver pearl catch in her right hand.
She is wearing a pale blue water witch mask fitted with multiple fishscales, a sapphire moire silk pelisse striated with myriad blue hues, a driftwood and pearl pendant carved with a stormy seascape, a backless pearl-hued silk gown with whorls of silver embroidery on the pleated train, an elegant silver ring inset with tiny sapphires, and some soft aqua silk slippers with pearly bead-tipped points.
