Round Signature One-Piece Collar Shirt

Wear a Gentle Impression Through the Beauty of Curves.

The Story

What remains in someone's memory is not always a bold statement.

A gentle expression.

A natural gesture.

Time spent with someone special.

And the quiet kindness that returns to memory long afterward.

The Round Signature One-Piece Collar Shirt expresses this enduring sense of kindness through the graceful curves of its design.

In the morning light, throughout the working day, while traveling, or during a special evening.

Unconfined by any particular occasion, it is designed to bring out the most beautiful expression of the person wearing it.

A shirt created not to demand attention, but to leave a lasting impression through gentleness, refinement, and effortless style.

The Design

Round Signature is the iconic shirt design of Ryunosuke TOKYO.

A rounded collar.

A softly flowing, curved front placket.

A gently rounded hem.

Buttons thoughtfully positioned along the curved line.

From collar to hem, these continuous curves lend a sense of softness and refinement to the wearer's appearance.

In this interpretation, Round Signature features a one-piece round collar.

The collar flows naturally into the body of the shirt, creating a soft, sculptural line from the neckline to the chest.

Recognized not by a logo, but by the silhouette itself.

This is Round Signature.

The Fabric

Crafted from Egyptian Giza cotton, selected for its supple texture, exceptionally smooth touch, and refined natural lustre.

The herringbone fabric is carefully woven on traditional shuttle looms, creating delicate variations of light and shadow.

From a distance, the fabric appears composed and understated.

Up close, the subtle dimensionality of the weave gradually reveals itself.

Its beauty comes not from decoration, but from the character of the material itself.

A fabric designed to remain in memory.

Everyday Elegance

A familiar city street.

A morning on the way to work.

An afternoon at a hotel.

An art gallery or restaurant.

A leisurely walk while traveling.

An evening with someone special.

There is no single occasion that defines where this shirt belongs.

Worn on its own, the distinctive curves of Round Signature create a quiet sense of individuality.

Beneath a jacket, the softly sculpted collar introduces an understated touch of elegance.

Wherever life takes you, the shirt is designed to bring out the beauty of the moment.

Never excessive.

Yet never forgotten.

Design Details & Craftsmanship

Round Signature

Ryunosuke TOKYO's signature shirt design, defined by its rounded collar, curved front placket, rounded hem, and buttons arranged along the flowing front line.

One-Piece Round Collar

A distinctive one-piece collar construction that flows naturally into the body of the shirt, creating a soft, three-dimensional line from the neckline to the chest.

Floating Interlining

Floating interlining is used in the collar, front placket, and cuffs.

Its natural fullness and soft structure enhance the graceful curves of the Round Signature design.

Turn-Up Cuffs

Elegant turn-up cuffs introduce depth and refinement to the sleeves, lending a distinctive character to the wearer's gestures.

Set-In Sleeve Construction

The sleeves are attached after the body has been assembled, creating natural shaping and dimensionality from the shoulders to the underarms.

Side Gussets

Reinforcing gussets are placed at both sides of the hem to strengthen areas subject to stress and reflect the attention to detail of traditional shirtmaking.

Split Yoke

A split-yoke construction at the back improves the fit across the shoulders and creates a more refined, three-dimensional silhouette.

Tailoring & Size

Designed with a refined, comfortable silhouette that is neither overly fitted nor excessively loose.

The proportions are carefully balanced to maintain an elegant appearance when worn on its own.
