FAQs
What silhouette is this prom dress?
It is a mermaid dress. The gown fits closely from the bodice to the knee area, then flares into a tiered ruffle skirt for a dramatic evening shape.
Is it a good fit for plus-size shoppers?
Yes. This style comes in US2–US16 and 16W–26W. Mermaid dresses follow your curves, so we recommend ordering by your bust, waist and hip measurements.
Can I walk and dance comfortably in a mermaid dress?
The skirt opens up below the hip and the ruffled tiers add movement, which helps with walking and photos. For long dance sets, choose comfortable heels and lift the hem slightly on stairs.
What shoes and jewelry go with it?
Black or metallic pumps and simple jewelry like stud earrings or a delicate necklace let the rhinestones stand out. The dress is shown here with black heels and a fine pendant, which are not included.
Can I machine wash this dress?
Yes. Wash on a gentle, cold cycle inside a mesh bag with mild detergent, then hang to dry. Avoid bleach and high heat.
Is this dress only for prom?
No. Besides prom, it works for formal dances, galas, weddings and other black-tie or cocktail-formal events.
Which colors are available?
Black, Burgundy, Champagne Gold, Dusty Rose and Navy Blue. Choose your color and size from the options above the Add to Cart button.
