What is a Mermaid Style Dress Called?

A mermaid-style dress is often referred to as a fishtail dress because of its distinctive silhouette that mimics the shape of a mermaid’s tail. This style is known for its fitted bodice that hugs the body down to the knee or lower, where it flares out dramatically, creating a striking, glamorous look. The term "fishtail" is sometimes used interchangeably with "mermaid" to describe this eye-catching dress style.

Fit and Flare vs. Mermaid Style Dresses: What’s the Difference?

While both fit-and-flare and mermaid dresses create a similar silhouette, there are key differences. Fit-and-flare dresses typically have a more gradual flare starting above the knee, offering a less dramatic look. Skater dresses or short A-line dresses can be considered a fit 'n' flare silhouette. In contrast, mermaid dresses fit closely to the body down to the knees or lower before flaring out, creating a more dramatic and defined hourglass shape. Fit-and-flare dresses tend to be more versatile and easier to wear, while mermaid dresses are bolder and more statement-making.
