Cottelli PARTY Long Dress XL — long black dress with a silver shimmer

Description

The Long Dress XL by Cottelli PARTY is a long, fitted black dress with a silver shimmer, made for striking evening looks. Its glossy surface catches the light beautifully, while the open back and shoulders give the silhouette a sense of lightness and visual appeal.

The design pairs a dressy aesthetic with details that help flatter the figure. The soft, stretchy fabric hugs the silhouette for a more comfortable fit, while built-in cups with underwire support the décolleté and shape its line. This cut lets you wear the dress as a statement piece on its own, without needing extra styling elements.

Silver effect and a defined silhouette

The standout feature of the Long Dress XL is the combination of a black base with a silver shimmer. Under light, the material takes on a distinctly glamorous character, making the dress ideal for evening outfits, photoshoots, and special occasions where a bold presentation matters. The long, body-hugging shape visually elongates the silhouette, while the soft, stretchy texture helps keep you free to move.

Halter neckline and open back

The dress features a halter neckline with a hook closure. The design also allows for a version with the straps crossed at the front, so you can style the same dress in different ways. Additional adjustable straps can be detached, letting you change the overall vibe depending on how you choose to wear it.

Front slits and fit

Two high slits at the front make the long skirt more dynamic and easier to walk in. They add a bold touch without hiding the fitted cut. The open shoulders, bare back, and décolleté line form a daring composition, while the black color keeps it a versatile staple for any evening wardrobe.

Material and composition

The dress is crafted from a soft, stretchy fabric made of 90% polyester and 10% elastane. This blend supports the material’s flexibility and helps the dress follow the lines of your body. Keep in mind the form-fitting design, the open areas, and the XL sizing: this model is intended for a defined fit, not a loose one.

The Cottelli PARTY Long Dress XL is for anyone looking for a long black dress with a shimmering effect, an open back, cup support, and two front slits. The adjustable elements and the option to change the strap placement add versatility, while the stretchy fabric helps you adapt the look to whatever occasion you choose.
