A polished plus size mermaid midi cocktail dress designed to celebrate curves with clean, confident lines. Élodie pairs a modern square neckline with soft flutter sleeves and a close-fitting silhouette before opening into a beautifully flared lower skirt. The result is feminine and striking without relying on excessive embellishment—an elegant choice for weddings, cocktail events and special celebrations.
Why This Dress Works Beautifully on Curvy Figures
The square neckline creates a strong, open frame around the décolletage while the broad shoulder placement gives the upper body visual balance. Soft flutter sleeves add graceful upper-arm coverage without hiding the shape of the dress.
Through the body, long vertical seams create an uninterrupted line from bodice to skirt, while the defined waist gives the silhouette structure. The close-fitting skirt follows the curves through the hip before releasing into the flared lower section, creating the characteristic mermaid shape and bringing movement and proportion to the hem.
Rather than adding volume around the waist or abdomen, the design keeps this area exceptionally clean. This makes the dramatic lower flare the focal point and gives the whole dress a streamlined, sculpted appearance.

Fabric & Feel
The fabric has a smooth, clean surface with enough visual structure to hold the fitted silhouette and sculpted flared hem. The uncluttered finish allows the architectural neckline and curved mermaid shape to remain the focus.
Fit Information
Élodie has a fitted silhouette through the bodice, waist and hips before releasing into a fuller flared hem.
The square neckline provides open décolletage while retaining substantial shoulder coverage. Flutter sleeves provide soft coverage over the upper arms, while the clearly defined waist and vertical bodice and skirt lines visually lengthen the body.
The skirt is designed to follow the figure rather than hang as a straight column, with the lower flare creating movement and balancing the fitted upper portion.
