Complete your look

This one-shoulder sequin mini cocktail dress is your go-to choice for parties, holiday events, and nights out. Featuring an asymmetrical one-shoulder neckline, a single long sleeve, all-over sparkling sequins, and a tie-waist belt, it is designed to turn heads and flatter your figure in sizes S through XXXL.

Why You'll Love It

  • All-Over Sequins: Head-to-toe sequin coverage catches the light from every angle, delivering a glamorous, eye-catching shine.
  • Asymmetrical One-Shoulder Design: The single long sleeve and bare opposite shoulder create a bold, modern silhouette that stands out in any crowd.
  • Tie-Waist Belt: A built-in self-tie belt cinches the waist and adds a polished, feminine shape to the mini silhouette.

Perfect For

Style it with strappy heels and a metallic clutch for a New Year's Eve party or formal event. It works equally well for a bachelorette celebration, holiday cocktail hour, or a glamorous night out on the town.

Care Instructions

  • Hand wash in cold water.
  • Do not bleach or wring.
  • Lay flat or hang to air-dry away from direct sunlight.
  • Cool iron on reverse if needed, avoiding the sequins directly.
