Rose Pink Off-the-Shoulder Sequin Ruched Mermaid Prom Dress

Catch the light with every step in this sequin mermaid gown. Hundreds of circular sequins shimmer across a fold-over off-the-shoulder neckline, while a dramatic ruched wrap detail sweeps across the waist for a flattering, figure-defined fit. The bodice flows seamlessly into a mermaid skirt that flares below the knee, finished with a thigh-high slit and a graceful sweep train. Made in sizes from US 2 up to plus size 26W and in more colors, it's a showstopping pick for prom and every formal occasion. Browse more styles in our prom dresses collection.


Product Silhouette

A true mermaid silhouette that skims the body through the bust, waist, and hip before releasing into a dramatic flare below the knee. The fitted shape highlights every curve, while the flare and sweep train add drama with every step. Looking for this style in satin instead? See our off-shoulder satin prom dresses.

Material

Circular sequins are densely hand-applied over a soft mesh base for all-over sparkle and fluid movement. The dress is fully lined in a double-layer construction with clean, hidden interior seams, so it fits smoothly against the body with no show-through.

Occasions

  • Prom and formal school dances
  • Black-tie galas and evening events
  • Pageants and red-carpet moments
  • Winter formals and holiday parties
  • Looking for the newest arrivals? See our 2026 and 2027 prom dresses

Care Instruction

  • Do not machine wash — the circular sequins can loosen and shed with agitation
  • Spot clean gently with a damp cloth as needed
  • Professional dry clean recommended for a full clean
  • Do not bleach, wring, or tumble dry
  • Hang on a padded hanger between wears

Size and Fit

Available in sizes US2-US16 and 16W-26W. The fitted bodice and waist hug the body closely before releasing into the mermaid flare, so we recommend sizing according to your natural measurements rather than your usual ready-to-wear size. Please reference our detailed size chart for exact bust, waist and hip measurements before ordering.

Styling Tip

Let the sequins do the talking — keep jewelry simple with delicate drop earrings and a thin bracelet. Pair with strappy metallic or nude heels, and a swept-back or half-up hairstyle to show off the off-the-shoulder neckline.

Frequently Asked Questions

How long will this sequin mermaid prom dress ship to the United States?

Production takes 3-5 business days. Standard shipping takes 6-8 business days (about 8-10 calendar days), and expedited shipping takes 3-5 business days (about 5-7 calendar days). Major holidays may lead to delivery delays, so order early for your prom date.

Is free shipping offered for this off-the-shoulder sequin dress in the USA?

Free shipping applies for most U.S. states. Hawaii, Alaska and Puerto Rico are excluded from the free-shipping offer. See our shipping policy for details.

Can I return this sequin mermaid prom dress?

Standard-size items can be returned within 30 days after you receive your package. Items must be unwashed, free of stains, kept in original condition with no sequin loss, and have the clothing tags intact. See our return and refund policy or visit our FAQ page for more help.

Does this dress run true to US formal dress sizes, and is it available in plus sizes?

This dress follows US women's formal sizing from US 2-US 16, and it is also available in plus sizes 16W-26W, so the same design is offered across the full size range. We strongly recommend measuring your bust, waist and hips in inches and comparing them with our size chart, rather than relying only on your everyday casual-clothing size.

Is this dress good for prom?

Yes. The off-the-shoulder neckline, all-over sequin sparkle, and dramatic mermaid silhouette make it one of our most eye-catching prom styles, and it also works beautifully for black-tie events and galas.

Can I machine wash this dress?

No. This dress should not be machine washed, as the circular sequins can loosen or shed with agitation. We recommend spot cleaning gently with a damp cloth, or taking it to a professional dry cleaner for a full clean.

How high is the slit, and how does the dress close?

The dress features a high thigh slit for ease of movement and dancing, and closes with a back zipper for a secure, comfortable fit.

Does this dress have a lining?

Yes. The dress is fully lined with a double-layer construction, so all seams are finished on the inside and nothing shows through from the outside.

What shoes pair well with this dress?

Strappy heeled sandals in a metallic or nude tone complement the sequin sparkle beautifully without competing with it.
