What a Mermaid Silhouette Actually Looks Like

A quick note before you shop: on PromGirl, "mermaid" is a long, floor-length gown style -- fitted through the bodice and hip, then flaring out near the knee or lower calf, closer to how the term is used for prom and evening gowns. It's a genuine, in-stock silhouette on the site, and it works well for homecoming at schools with a more formal or black-tie-optional dress code, or for anyone who simply wants a longer, more dramatic look than the typical short homecoming dress.

If your homecoming is more casual and you want a fitted look in a shorter, homecoming-length dress instead, PromGirl's short styles are catalogued as "bodycon" or "fitted" rather than mermaid -- see the Trending picks above, or our Best Corset Homecoming Dresses 2026 and Best Unique Homecoming Dresses 2026 guides for more fitted, short options.

Mermaid vs. A-Line: Which Fits You Better?

A mermaid dress is form-fitting through the hip before flaring near the knee, which shows off your shape but fits closer to the body than most other silhouettes. If you'd rather have a dress that flares gradually from the waist and is more forgiving through the hip and thigh, see our Best A-Line Homecoming Dresses 2026 guide instead.

Plus-Size Mermaid Option

The Ladivine CD0214C above is the plus-size cut of the CD0214, sized 16W-28W in 6 colors. For more plus-size picks across other silhouettes, see our Best Plus Size Homecoming Dresses 2026 guide.
