Boutiquehomecomingdress takes a spin on this classic design and adds an extra level of sparkle to each Mermaid Homecoming Dress that is sure to impress! The mermaid dress is a popular gown that, as the name suggests, is an evening gown shaped like a mermaid. It features a form-fitting bodice and a skirt that is designed to resemble a mermaid's tail in silhouette. The dress is close-fitting until the knees where the skirt starts to flair out. Depending on the dress, the skirt may or may not be the same color or texture.
