Sienna Maxi Dress | Black Maxi Dress, Long-Sleeve Maxi Dress

The Sienna Maxi Dress is a black maxi dress designed with an off-the-shoulder neckline, a soft polyester and spandex blend, and a refined full-length pencil silhouette. This long-sleeve maxi dress features a high waist, a sculpted fit, and dramatic puff sleeves that add modern volume to an elegant evening profile.

Designed for a clean, elongated shape, this style combines a body-hugging fit with balloon sleeves and an open-back detail for added contrast. The fabric offers structure with flexibility, while the off-the-shoulder neckline creates a polished finish suitable for formal dresses and elevated event attire.

Ideal for cocktail hours, formal evenings, and wedding guest dress styles, this maxi dress pairs easily with minimal heels, sculptural jewelry, or a compact clutch. The silhouette transitions seamlessly from evening occasions to curated event wardrobes with an elegant, fashion-forward look.
