The mermaid gown is a body-hugging silhouette with a skirt that flares below the knee. The mermaid silhouette highlights feminine curves, making it one of the best dress styles for hourglass figures. This style can also add feminine curves to a straight figure.
Mermaid gowns are glamorous and sexy. Even with a high neck and/or long sleeves, they still look alluring, glamorous and sexy, without showing too much skin.
