Off shoulder. Ruffle cape. Mermaid drama.

This mermaid gown is a princess dress for girls with a wide off-shoulder ruffle, a fitted body and a long skirt with a front slit and a sweeping train.

Bold on Stage
The ruffle neckline and long train make a dramatic impression in photos.

Easy Movement
A lined bodice and front slit let her walk and pose comfortably.

Three Colors
Pick burgundy, red or black for pageants, concerts and holiday events.

It is a striking girls formal dress for pageants and runway shows, and a festive girls christmas dress in red or burgundy. Add sparkly shoes and a simple hair accessory for the stage, then a soft wrap for the trip home. It turns every big moment into a memory worth keeping.
