Ami alexandre mattiussi/ Oversized Long Dress Shirt White

AMI Alexandre Mattiussi. Founded in Paris in 2011 by designer Alexandre Mattiussi, the brand offers a refined, sophisticated collection that seamlessly blends French elegance with real-life wear. Introducing an oversized long dress shirt that beautifully elevates the sartorial craftsmanship—an area where the designer, who built a career at Dior and Givenchy, truly excels—and a distinctly modern, relaxed sensibility.

At first glance, it appears to be a simple white shirt, yet every aspect—details, fabric selection, and the shaping of the silhouette—has been meticulously calculated to achieve perfection.

The standout feature is its crisp, clean presence, made luxurious with a sumptuous 100% cotton fabric, paired with an oversized silhouette that offers generous ease in both the chest width and the body length. Drop shoulders with an intentionally lowered shoulder line and deep center box pleats placed beneath the yoke at the back create a three-dimensional effect that seems to hold air when worn, and each time you move, it draws an elegant drape. The premium broadcloth fabric, balancing an ideal amount of structure with a smooth feel against the skin, enhances the crisp brilliance of its clean white tone.

At the chest, a neat patch pocket is added, bringing a touch of casual ease into the tailoring of a classic dress shirt. The inner label features a special insert reading “Fabriqué au portugal (avec amour),” indicating that it was produced with love in Portugal’s finest factories—an attention to detail that encapsulates the brand’s craftsmanship and aesthetic sensibility.

When styling, the possibilities are limitless. The minimalist, mode-like look of simply fastening the buttons to create a mini dress silhouette is, of course, a natural choice, but you can also freely build layered outfits by pairing it with shorts or slim trousers. Add vivid contrast with red leather gloves and bags, or rugged boots; or slip it under a tailored jacket so the shirt fabric is boldly revealed from the hem and cuffs. You can also wear it with the front buttons left open for a look that feels like a light outer layer.

Designed to be cherished as a long-term wardrobe staple that anchors your styling—from high fashion to real-life everyday wear—regardless of eras or trends, this is the kind of top-tier piece you will want to keep on hand.
