About the Collarless Layered Jacket

Design

This jacket features a striking design that appears as if a vest is layered over a one-button collarless jacket.
Yet, it retains the elegance and minimalism typical of a tailored jacket, making it suitable for both set-ups and casual wear on its own.

• Layered Hem: Asymmetrical layers create visual variation
• Pocket Construction: Slash pockets on both sides and a change pocket instead of a chest pocket
• Unstructured Build: No shoulder pads, creating a natural form
• Neckline: Wide opening that flows smoothly into the button area for a clean look
• Lining and Sleeves: Cotton body and smooth polyester sleeves
• Elbow Darts and Rounded Cuffs: Structured for mobility and ease of wear

Silhouette, Size, and Fit

The silhouette is sharp with a relaxed feel.
Because the waist is not tightly shaped, it's easy to pair with looser bottoms.
The shoulders are designed to avoid tightness, so you can comfortably layer cut-and-sew tops or shirts underneath without bulkiness.
The slightly short length makes it perfect with wide pants or voluminous denim.

Staff Comments:
The shoulders are clean and the sleeves taper slightly toward the cuffs, offering balance between relaxation and neatness.
Materials are chosen with the season in mind, and pattern design minimizes skin contact for better comfort. The jacket offers great comfort while maintaining a stylish silhouette.
Although highly designed, it can be worn casually like a cardigan—perfect for relaxed seasonal outfits.

Styling Suggestions for Each Variant

The look is styled with Hakama trousers.

Two types of trousers in the same material are also available, allowing you to enjoy a set-up style.

If used on its own, it can be combined with trousers of different textures.

Linen-Viscose with Unique Depth

This style offers a more expansive colour range than black.

You can change the impression depending on the colouring of the innerwear and trousers, and there is more flexibility than meets the eye.

Of course, set-ups are also recommended.

How to Choose Between the Two Models

Both options have a matte, understated look, but differ slightly in feel and tone. Generally, we recommend the following.

• Summer Wool：A “refined” impression from the crisp, thin wool texture
• Linen × Viscose：A “decadent and deep” look thanks to the dye variation and linen’s natural wrinkles

Both are lightweight and breathable, ideal not just for spring/summer but also for air-conditioned environments or seasonal transitions.
If you want a cleaner, more polished style, go for summer wool. If you prefer character and uniqueness, linen-viscose is the one for you.
