Sienna | Women’s Square-Neck Asymmetric-Waist High-Slit Fall Wedding Guest Maxi Dress

The Sienna Women’s Square-Neck Asymmetric-Waist High-Slit Fall Wedding Guest Maxi Dress is your go-to choice for weddings, galas, and glamorous formal evenings. Cut with a structured, corset-style bodice, a clean square neckline framed by wide straps, and a richly pleated skirt that falls asymmetrically into a thigh-high side slit, this gown is perfect for women who want a sculpted, hourglass silhouette with dramatic movement built in.

Why You'll Love It

• Sculpted Corset Waist: The structured, fitted bodice cinches the midsection for a naturally flattering hourglass shape without extra shapewear.
• Asymmetric Pleated Skirt: Cascading pleats fall unevenly across the skirt for a fluid, floor-length drape with a modern, sculptural edge.
• Square Neckline & Wide Straps: A straight-cut square neckline paired with substantial shoulder straps creates a polished, sophisticated frame for the décolletage.

Perfect For

Standing out as a wedding guest dress, styling with strappy heels and statement earrings for a black-tie gala, wearing to an upscale cocktail party, or making an entrance at prom night.

Care Instructions

• Hand wash or machine wash on a delicate cold cycle.
• Do not bleach.
• Hang to dry or lay flat, and avoid the tumble dryer to preserve the pleated skirt shape.
• Iron on a cool setting from the reverse side if needed.
