Tailored for brides wearing mermaid or trumpet-style wedding dresses, this fishtail crinoline underskirt is engineered to accentuate your curves while providing structured support. Unlike generic petticoats that flatten the mermaid’s signature “flare-at-the-knee” shape, our design hugs your hips and thighs before flaring gently—ensuring your dress looks sleek, sculpted, and red-carpet-ready from ceremony to reception.

Mermaid gowns rely on sharp, defined curves for stunning photos. Our underskirt’s contoured design prevents sagging, so your dress maintains its shape in outdoor shots (even in light wind) and indoor portraits. The subtle flare at the knee adds dimension, making your silhouette pop in close-ups and full-body shots.
For events where you’ll sit, stand, and dance: The underskirt’s stretchy fabric moves with you—no tightness around the thighs when sitting, and no bunching when dancing. It also prevents the dress from clinging to your legs, keeping you comfortable and confident all night.
• Contoured Fishtail Shape: Designed to follow the mermaid/trumpet gown’s silhouette—fitted through the hips/thighs, with a gradual flare starting at mid-thigh (not too high, not too low).
• Multi-Layer Support: 3 layers of soft tulle (plus a thin elastic lining) add volume without bulk. The top layer is ultra-fine to avoid showing through sheer wedding dress fabrics.
• Non-Slip Waistband: Wide, silicone-lined elastic waistband that stays in place—no sliding down during movement, even if you’re wearing shapewear underneath.
• Tulle Layers: 90% Nylon (soft, breathable, and has slight stretch) + 10% Spandex (enhances flexibility for movement).
• Lining: 95% Polyester + 5% Spandex (smooth, moisture-wicking, and prevents irritation).
• Reinforcement Stitches: High-tensile thread at the flare seams to prevent tearing from repeated movement.
