The mermaid wedding dress is one of the most iconic silhouettes in bridal fashion — and for 2026, the designs are more beautiful than ever. A mermaid dress follows the body from chest to knee, then opens into a dramatic flare that trails behind you as you walk. It is sleek, confident, and genuinely breathtaking from every angle — especially from behind, where the flare creates one of the most photogenic shapes in all of bridal fashion.
Wondering whether a mermaid or a trumpet is right for you? Our mermaid vs trumpet guide explains exactly what separates the two. And for practical advice, read our guide on what to wear under a mermaid wedding dress.
Why Mermaid Wedding Dresses Are So Loved
A mermaid dress creates a silhouette that is impossible to forget. The way it follows the natural shape of the body and then opens dramatically at the hem — that contrast is what makes it so striking. It photographs beautifully at every angle, it moves gracefully when you walk, and it gives the whole wedding a sense of elegance and occasion. Where the flare starts changes the look completely: a higher flare is more dramatic, a lower flare is more fluid and wearable. All our mermaid dresses are made to your measurements, so the placement can be adjusted perfectly for you.
Aria — Fitted Lace Mermaid with Detachable Train
Aria is the definitive lace mermaid. The strapless corset bodice has a beautiful low waist seam that gives the dress incredible definition, and the fine lace runs consistently from chest to hem without interruption. The detachable tulle train adds ceremony drama and then removes cleanly for the reception, so you can dance freely without losing any of the elegance. See the Aria fitted lace mermaid.
Aria — Strapless Lace Mermaid with Basque Waist
This version of Aria features a basque waist — a deep, pointed V at the front of the corset that creates a beautifully elongated and romantic silhouette. The mermaid flare begins just below the knee and opens into a full, sweeping lace train. Every detail of this dress is designed to make you feel completely stunning. See the strapless basque waist mermaid Aria.
Tonika — Embroidered Lace Mermaid
Tonika is a dress you fall in love with up close. The embroidered lace is three-dimensional — the floral pattern is raised and textured, catching the light in a way that flat lace simply cannot. The heart-shaped corset bodice adds an extraordinary romantic quality, and the mermaid skirt opens into a dramatic lace train. This is a dress that rewards every guest who gets to see it in person. See the Tonika embroidered lace mermaid.
Viola — Halter Neck Drop Waist Mermaid
Viola is a truly special wedding dress. The halter neck creates a dramatic, beautiful open back — one of the most stunning details possible in a bridal gown — and the drop waist seam gives the silhouette a graceful, elongated quality. The detachable tulle skirt transforms the look completely: full and dramatic for the ceremony, sleek and body-skimming for the reception. For more on this neckline, see our halter neck guide. View the Viola halter neck mermaid.
Belle — Elegant Mermaid Mikado with Detachable Train
Belle is sleek, modern, and effortlessly elegant. Made in structured mikado fabric, the mermaid silhouette holds its shape beautifully throughout the entire day — perfectly precise at midnight as it was in the morning. The detachable train makes it easy to transition from ceremony to reception without a single compromise on elegance. Read more about why mikado is such a wonderful fabric for wedding dresses. See the Belle mikado mermaid dress.
Katrine — Sleek Crepe Mermaid
Katrine is pure, confident elegance. The crepe fabric drapes beautifully over the mermaid silhouette — smooth, matte, and completely stunning in its simplicity. There is no lace, no beading, no decoration: just the perfect line of the dress and the way it moves. Katrine is a dress that lets you be the focal point, and it photographs beautifully in every light. For more on crepe as a bridal fabric, see our lace vs crepe guide.

Florine — Floral Deep V Mermaid with Open Back
Florine is one of the most photographed dresses we make, and it is obvious why. The deep V neckline and dramatically open back create an entrance like no other, while the floral lace appliqués add a beautiful softness and texture. The mermaid silhouette completes the picture. It is a dress for evening weddings, destination celebrations, and any bride who wants to feel truly extraordinary. See the Florine floral deep V mermaid.
Sienna — Long Sleeve Floral Lace Mermaid
Sienna is breathtaking. The floral lace long sleeves create a silhouette that is dramatic, refined, and completely unforgettable — especially at a church ceremony or a winter wedding where the covered look feels perfectly right. The mermaid flare at the hem completes a silhouette that is elegant from every angle. For a full look at sleeve options, see our long sleeve vs sleeveless guide.
