Keep it long, treasure it long.

The longer sleeves add a sense of balance to the overall look.

As we grow older, we find ourselves choosing clothes not just because we want to wear them, but because they feel good to wear.
TSUYUMI offers simple yet striking pieces that perfectly capture that feeling for mature women. Each design balances a sense of cleanliness and sophistication without chasing fleeting trends. With refined materials, elegant silhouettes, and thoughtful pattern construction, the collection evokes that subtle charm of “simple, yet somehow special” — understated, yet impossible to overlook — all with a touch of handcrafted warmth.

A T-shirt with effortless presence

This long-sleeve T-shirt features a rounded collar finished with a wide self-fabric binder. The same binder finish is used on the cuffs and hem, adding a sense of structure and gentle volume. Designed with a drop shoulder and slightly elongated sleeves, it can be styled with the cuffs softly gathered for a relaxed look. The high-low hemline creates a balanced silhouette that flatters the body.

Made from cotton fabric that combines supple drape with a soft firmness, it feels gentle against the skin and is comfortable whether worn alone or layered. Its relaxed sizing pairs beautifully with voluminous bottoms.

Though simple in appearance, every detail has been carefully considered. This T-shirt blends naturally into your everyday wardrobe, offering timeless comfort and quiet refinement — a piece to be worn and loved through the seasons.

Thoughtful design for the modern woman

As we mature, we often find that fewer things truly suit us. We may lose interest in trends, yet still want to look composed and refined — without the fuss of overstyling.
Rather than following fast-changing fashion, TSUYUMI continues to create pieces that feel good to wear and remain timeless. Its designs are minimal and enduring, with subtle touches of craftsmanship that lend depth and character.

Guided by the designer’s wish “to create items that never grow tiresome,” TSUYUMI prioritizes silhouette and comfort, using only high-quality materials. Each piece features meticulous detailing and functional pattern work that make dressing a joy. Some garments even incorporate hand-sewn elements, bringing a warmth and individuality that mass production could never replicate.

Clothes that gently accompany you

TSUYUMI was founded in New York in 2004 by Japanese designer Ms. Iizuka. After working as a fashion designer in Japan, she moved to New York and began creating hats — a process that soon reignited her passion for craftsmanship. Her pieces quickly gained attention among those with a keen eye for design, marking the beginning of the brand’s journey.

Upon returning to Japan, she expanded into clothing, creating garments in small batches with care and precision. Each piece embodies the brand’s ethos of “effortless elegance” — clothes that make you look stylish the moment you put them on. Through hand stitching, specialized machines, and expert pattern techniques, every garment reflects a dedication to craftsmanship and timeless wearability — qualities that allow TSUYUMI’s creations to be cherished for years to come.
