D.C.WHITE
D.C.WHITE / Summer Wool Unstructured Jacket
The navy blazer—an icon of Ivy style—redefined through a contemporary lens. The answer lies in lightness.
While a typical tailored jacket weighs between 700–1000g, this piece comes in at approximately 300g—comparable to a midweight long-sleeve T-shirt.
Constructed without lining or excess interfacing, and refined through techniques such as hidden stitching and french seams, every detail is considered for weight reduction. Yet visually, it remains a classic navy blazer.
A piece that honors tradition while quietly shedding the weight of convention.

D.C.WHITE
A Japanese brand that reinterprets the traditional clothing culture of the American East Coast through a modern lens. Each piece is created with a sincere dedication to craftsmanship—an honest pursuit of garments made with care and intention.


The assurance of high-twist wool by Canonico
The fabric is a high-twist wool tropical cloth from Italy’s Canonico. It carries a refined luster while remaining breathable and comfortable, even in Japan’s humid climate.
Dry to the touch and remarkably light—yet never insubstantial. It achieves a delicate balance, maintaining the dignity of a tailored jacket while remaining easy to wear through the summer months.
Because the structure is formed without relying on interlinings, the quality of the fabric directly defines the garment. The uncompromising choice of material is part of what sets this piece apart.
Sculpted Without Interlinings
The standout feature of this jacket is its construction—achieving a three-dimensional form without any interlinings.
The lapel, gently curved in an S-shape, rolls naturally under its own weight. By borrowing a technique often seen in womenswear, it perfectly balances lightness with sculptural elegance.

The sleeves are constructed with inward seams, allowing them to naturally curve forward. Even without internal structure, the silhouette follows the body comfortably.
A chest pocket sits on the left, with practical waist pockets on both sides.
A rear vent at the hem ensures ease of movement while maintaining a clean, elegant line.
Light in weight, never in presence
Despite its minimal construction, the silhouette never feels lacking.
Rather than a restrictive fit, it offers just enough room to move comfortably—easy to wear even in midsummer, while maintaining a composed, tailored appearance.
Effortless over a T-shirt, yet equally refined with a shirt and slacks. Rooted in the tradition of the navy blazer, it integrates seamlessly into a modern wardrobe—quietly balancing heritage and ease.
