This dress features a beautiful blue gradation. The soft fabric creates a lovely effect, like waves on the sea, when it moves. It's a size S, but fits like a size 9 (M). This is a mini version of the dress worn by Masami Nagasawa, Amika, Miyu Sakihi, and others. Gradation Color V-Neck Drape Flare One-Piece Mermaid
