At Adrianna Papell, our mermaid dresses are designed to celebrate your shape with elegance and drama. From sleek fishtail gowns to embellished evening styles, each piece is crafted to flatter, sculpt, and make a statement.

What Is a Mermaid Dress?

A mermaid dress features a sleek, body-skimming fit through the bodice and hips, with a dramatic flare starting at the lower thigh or knee, evoking the elegant shape of a mermaid’s tail. Also known as a fishtail dress, it emphasizes curves and adds dramatic flair to formal wear.

Often confused with a trumpet dress, the key difference lies in where the flare begins:

Mermaid dresses flare out below the knee.
Trumpet dresses begin to flare around mid-thigh.

This close-fitting shape is what gives mermaid gowns their signature, red carpet-ready appeal.

When Should You Wear a Mermaid Gown?

The beauty of the mermaid silhouette is its versatility, it works for a range of high-impact events. Here’s where to wear one:

Cocktail or Evening Parties: Evening mermaid dresses in shorter lengths or sequin mermaid dresses are a dressy yet elegant choice.
Adrianna Papell’s sequin mermaid dress collection features figure-flattering designs with just the right amount of sparkle, ideal for making a stylish statement at any evening event.

Weddings: A white mermaid dress or trumpet wedding dress is a timeless bridal choice, offering elegance with a modern twist.
Prom: Go bold with a black mermaid prom dress or opt for color and sparkle to bring drama to your big night.
Formal Galas: Formal mermaid dresses in luxe fabrics like satin or beaded mermaid dresses are perfect for upscale events.
Red-Carpet Events or Balls: A mermaid ball gown delivers maximum volume and impact, ideal for charity galas or couture moments.
Theme Events: A mermaid theme dress with iridescent fabrics or shell details makes a playful choice for costume or fantasy-themed parties.

Whether you're attending a formal function or dressing to impress, the mermaid silhouette adapts to your style and the event's dress code.

Which Body Types Look Best in a Mermaid Dress?

The mermaid dress is known for its figure-hugging silhouette, but it can work for many body types when styled correctly.

Hourglass Figures: This style was made for hourglass shapes. It accentuates the waist and highlights balanced curves.
Pear-Shaped Bodies: The flared skirt helps balance wider hips, while embellishments or structured bodices draw the eye upward and highlight the waist.
Athletic Frames: Create the illusion of curves with details like ruching, layered fabrics, or off-the-shoulder necklines. The flared hem adds volume to the lower body for a more balanced silhouette.
Plus-Size Figures: Mermaid dresses are a great option for plus-size bodies, as they accentuate curves and create a defined silhouette. Look for styles with built-in support, structured fabrics like mikado or crepe, and vertical seaming or paneling to elongate the figure and enhance natural shape.

The key is tailoring. No matter your body shape, the right fit makes all the difference.

How to Style a Mermaid Dress

Styling a mermaid outfit is all about enhancing the silhouette and letting the dress speak for itself. Here’s how to pull it all together:

1. Shoes:

Heels are a must. The snug fit and dramatic hem call for elevation. Choose closed-toe pumps or strappy heels that complement the dress length.

2. Accessories:

Keep jewelry minimal, especially if the dress features embellishments. Statement earrings or a bold cuff bracelet are often enough.

3. Hair & Makeup:

Slicked-back buns, voluminous curls, or old-Hollywood waves pair well with the glamour of a mermaid dress. Go for bold lips or dramatic eyes, but not both.

4. Outerwear:

For winter or formal events, choose a cropped faux fur wrap or structured blazer that won’t hide the waistline.

5. Bags:

Choose a clutch or small handbag. Anything oversized can throw off the balance of the silhouette.
