Story
Lumina works in a mermaid salon, customizing hairstyles. She gets the chance to attend the royal ball, so her friends give her a gown fit for a princess.

Lumina has long blonde hair with pink highlights. In her 'princess attire', she wears a necklace made by three rows of multicolor pearls: yellow, violet, pink and white, with a bigger white pearl in the middle of the lower row. Her bra is pink and strapless with white pearls on both edges and two chains made of the same type of pearls in the lower part. In the middle of her bra there are white pearls that form a flower with six petals.

Her tail, from the waist to the fin, goes from pink to violet, then orange and violet again. Her fin is big and bright pink; the whole tails is decorated with yellow, violet, white and pink pearls forming chains in the upper part that are all connected by a flower made of white pearls with a big violet one in the middle.
