About the Dress: Clarisse 811338

Clarisse 811338 is a fully sequined mermaid gown built for maximum impact at prom, a pageant, or any formal dance where you want to stand out. The dress is covered in sequins from the structured sweetheart bodice all the way down the fitted skirt to the trailing hem — no plain panels, no breaks in the sparkle. The dramatic detachable off-shoulder puff sleeves are the defining feature: wear them for a bold entrance, then remove them to reveal a completely open back for dancing.

Fit & Silhouette

Clarisse 811338 follows a true mermaid cut — the bodice and skirt hug the body closely through the bust, waist, and hips, then flare out below the knee into a sweeping train. There is no slit. The fit is tight and sculpted throughout, so this silhouette works best when you know your measurements. The structured bodice has internal boning that holds the sweetheart neckline securely in place, which matters when you're wearing a strapless look under the detachable sleeves. Sizing runs standard; see the FAQ on alterations if you're between sizes or on the petite or tall side.

Fabric & Detail

The entire gown — bodice and skirt — is covered in sequins over a jersey base. The sequin layer gives the dress a high-shine, mirror-like finish that reads as deep, rich black in-person and photographs with strong contrast and sparkle under event lighting. The detachable off-shoulder puff sleeves are made in the same sequin fabric and attach cleanly at the shoulder. The open back runs from the neckline down past the natural waist; a wide waistband panel sits at the waist before the skirt flares. The skirt ends in a short train that sweeps behind you as you walk.

Key Features

  • Fully sequined from neckline to train hem — bodice and skirt
  • Sweetheart neckline with internal boning for structured support
  • Detachable off-shoulder puff sleeves in matching sequin fabric
  • Full open back — the entire back is bare below the neckline
  • True mermaid silhouette: fitted through the hips, flares below the knee
  • Short train at the hem
  • Jersey base beneath the sequin overlay
  • Sleeveless once the puff sleeves are removed

Style & Occasion

Clarisse 811338 is made for prom and pageant-level events where an over-the-top sequin gown is exactly right. The two-look versatility — sleeves on for the arrival, sleeves off for the dance floor — makes it a strong choice when you want one dress to carry the whole evening. Pair it with strappy heeled sandals or pointed-toe heels to keep the line clean, and keep jewelry minimal: a sequin gown this bold does not need much help. A simple drop earring or a small stud works better than a statement necklace competing with the open back. A sleek updo shows off the back and the neckline together. Clarisse 811338 is currently photographed and available in black.
