Mac Duggal 21174 Strapless Sequin Peplum Open-Back Long Gown with Sweep Train
About the Dress: Mac Duggal 21174
Mac Duggal 21174 is a long strapless evening gown built around three distinct elements: a structured satin peplum bodice, a wide waistband accent, and a fitted full-length sequin skirt. The combination gives the dress a dramatic, editorial quality that works for prom, gala events, black-tie evenings, and formal occasions where you want to be remembered. Every section of the design does something specific — the peplum adds volume at the hip without sacrificing the sleek column line below, and the sequin skirt catches light with every step.
Fit & Silhouette
Mac Duggal 21174 is a fitted long gown. The silhouette is narrow and column-straight from the waist through the floor — this is not a mermaid or flare cut. The bodice is strapless and holds its shape through internal structure that keeps everything in place without straps. The peplum flounce sits at the waist and flares outward as a single layer, adding the illusion of a wider hip without changing the fitted column line of the skirt. The fit is close through the bust, waist, and hips. If you are between sizes, size up for comfort — a structured bodice that is slightly large can be taken in by a tailor; one that is too small cannot be let out.
Fabric & Detail
The bodice is constructed from satin with deep pleating built into the fabric, creating the structured, sculptural peplum shape. A wide waistband accent separates the bodice from the skirt and defines the waist sharply. The skirt is fully covered in sequins from the hip to the floor, and the sequin coverage is dense enough that the skirt reads as a solid surface of light rather than scattered sparkle. The back of the dress is open — the entire upper and mid back is bare, creating a strong contrast between the structured front and the exposed back. A back seam slit at the lower hem of the skirt allows for a full walking stride.

Style & Occasion
Mac Duggal 21174 is available in black. The black colorway makes the sequin skirt especially dramatic under event lighting — the sequins pick up every spotlight and flash. This gown is well suited to prom, black-tie events, galas, formal evenings, and any occasion where a fitted sequin gown reads as the right choice. The open back is a defining design element, so this dress suits someone who wants their back to be part of the look. It is not suited to events requiring modest coverage. Pair it with strappy heeled sandals, minimal jewelry, and a simple clutch — the dress itself does the work. A sleek updo works especially well given the open back and strapless neckline. At Marlas Fashions, we are an authorized Mac Duggal retailer and every dress is inspected before it ships.
