Description
About the Dress: Mac Duggal 50677
Mac Duggal 50677 is a long, structured satin mermaid gown built around two standout details: dramatic off-shoulder puff sleeves at elbow length and a fully open back that runs from the neckline to the waist. The sweetheart neckline sits at the front while the back drops completely open, creating a bold contrast of structure and exposure. This is a serious formal gown designed for events where presence matters — prom, galas, black-tie evenings, and formal dances.
Fit & Silhouette
Mac Duggal 50677 follows a true mermaid silhouette: the gown is fitted tightly through the bust, waist, and hips, then flares out below the knee into a dramatic sweep with a train. The princess-seam bodice is boned, which means it holds its shape and supports you without needing a separate bra. The fit through the body is close and structured — this gown is designed to contour. The puff sleeves sit off the shoulder at elbow length, adding volume at the top without restricting arm movement. Because this is a mermaid cut with a train, walking and dancing require short, fluid steps rather than wide strides, and the skirt moves beautifully when you do.
Fabric & Detail
The fabric is a structured satin — think mikado or faille-weight satin — which has a smooth, high-sheen surface with enough body to hold the dramatic puff sleeve shape without collapsing. There is no beading, sequins, or surface embellishment. The dress relies entirely on its construction and silhouette for its impact. The boning runs through the bodice via princess seams visible in the detail shots, and the open back is clean and uninterrupted — no lace-up, no corset closure, just a bare back from shoulder to waist.
Key Features
- Structured satin fabric with smooth, high-sheen finish

- Fully open back from neckline to waist
- Boned princess-seam bodice for built-in support
- True mermaid silhouette fitted through hips, flaring below the knee
- Floor-length with a trailing sweep
- No surface embellishment — silhouette and structure do the work
- Available in Purple, Black, Fuchsia, and Royal Blue
Style & Occasion
Mac Duggal 50677 is at home at prom, formal galas, black-tie events, and upscale evening functions. The open back makes it bold enough to stand out in a ballroom, while the structured satin and boned bodice keep it polished and elegant rather than party-casual. The open back suits evening and black-tie receptions beautifully; for more conservative wedding-guest settings, a wrap or tailored shawl pairs well with the look.
In terms of color: Purple photographs as a rich, saturated jewel tone. Royal Blue is vivid and electric. Fuchsia is a bright, warm pink that reads strongly under event lighting. Black is sharp and classic. All four colors hold their depth well under ballroom and stage lighting. If you want maximum drama under spotlights, Royal Blue and Fuchsia are the boldest reads; Purple and Black lean more refined.
For shoes, a pointed-toe or strappy heeled sandal in a matching or metallic tone works best — the train means you will want a heel that does not catch fabric. Keep jewelry minimal: the open back and puff sleeves already command attention. A simple pendant or small earrings let the dress speak. Marlas Fashions is an authorized Mac Duggal retailer, and every dress is inspected before it ships.
