Product Description
White Off-Shoulder 3D Floral Crystal Beaded Mermaid Prom Dress with High Slit and Sweep Train
The white Mercedes pulled up to the boulevard — and she stepped out like she owned every palm tree on the block. This white mermaid gown is pure Met Gala energy: sculptural 3D white floral appliques blooming across a sheer illusion sweetheart neckline, thousands of silver crystals and pearl beads cascading in swirling arabesque patterns across every inch of the fitted bodice, a dramatic off-shoulder ruffled organza sleeve that floats like a cloud, and a high slit that commands every cobblestone street it walks down.
Design Details
- Silhouette: Sculpted mermaid cut with a high slit and sweep train — form-fitting through the bodice and hips, with a dramatic leg reveal and trailing hem
- Neckline: Sheer illusion sweetheart neckline adorned with sculptural 3D white floral appliques blooming across the bust — the signature couture detail that elevates this gown
- Sleeve: Dramatic off-shoulder ruffled organza puff sleeve on one side — adds ethereal volume and movement, detachable for a sleeker look
- Bodice & Skirt: Sheer nude illusion mesh entirely covered in thousands of silver crystals and pearl beads in swirling arabesque and vine patterns — creates a full-body constellation effect from neckline to train
- Color: White silver — luminous, bridal-adjacent, and impossibly photogenic under golden hour sunlight, street lamps, and flash photography
- Accessories shown: Crystal floral headpiece, chandelier drop earrings, diamond tennis necklace, and red rose wrist corsage (sold separately)
Why You'll Love It
In front of a white Mercedes-Benz S-Class on a sun-drenched palm tree boulevard, leaning against the hood with a luxury shopping district behind you, or seated in the back of a luxury sedan holding hands — this gown was built for the moments that define your night. The 3D floral neckline creates an unforgettable first impression, while the full-body crystal beadwork ensures you sparkle from every angle all night long.
