YONETOMI NEW BASIC / Rigid Sea Island Cotton Horizontal Round Body Knit T-Shirt
Introducing a cotton knit T-shirt made from Sea Island cotton, known as the “jewel of fibers” and native to the West Indies. It features an elegant luster and smooth texture, and its ideal thickness prevents it from looking see-through even when worn alone.
Furthermore, the seamless round body design minimizes stress on the skin for a comfortable fit.
“Rigid knit” refers to a knit fabric that has not undergone any processing such as washing or dyeing, allowing it to age naturally over time. As a result, the texture and feel of the fabric can be customized to your preference depending on how often you wear it and how you care for it.
This T-shirt is the perfect example of a ‘knitwear that grows with you,’ combining elegance with durability and a comfortable fit that improves with wear. We invite you to experience this exceptional piece for yourself.




YONETOMI NEW BASIC
This knit project, by Yonetomi Seni, pursues basics that accompany "the new everyday" in a meaningful way. Using the expertise of a factory, it features thoughtful details and subtle arrangements, proposing everyday wear for new lifestyles.
Soft and Durable Premium Fabric
Made from 100% Sea Island cotton, known as the "jewel of fibers" in the West Indies, and custom-spun high-twist yarn for mid-gauge knitting, this piece is made with dense, smooth jersey knit.
Sea Island cotton fibers are 35mm-40mm long, significantly longer than regular cotton (20mm), resulting in a soft, durable fabric. The tight-knit construction creates a beautiful, silk-like sheen.
Unlike regular T-shirts, knit T-shirts offer superior moisture-wicking and breathability, making them perfect for the summer as they prevent visible sweat stains.
Made from 100% cotton with a smooth woven inner lining, it's perfect for those who are sensitive to wool's itchiness.
You can wash it by hand at home, and over time, the fabric softens, conforming to your body, making it a "growing knitwear" that you'll love for a long time.
Clean and Simple
The neckline features a neat, simple crew design. The lack of unnecessary decorations highlights the superior fabric.
The body is knitted in a seamless round body construction for a comfortable fit with no stress.
Elegant and Relaxed Silhouette for Adults
With a moderately relaxed fit and a slightly shorter length, it offers a neat and clean look.
This timeless silhouette ensures long-lasting enjoyment, free from trends.

● Staff (165cm/52kg) Body type: Slim Wearing: Size 2 The shoulder width was just right, and the body width had a comfortable amount of room. The sleeve length was about 4–5cm above the elbow, and the length covered about half of the hips. Depending on personal preference, if you want a looser fit, size 3 might be a good option. |

The sleeve length was about 2cm above the elbow, and the length covered about half of the hips. Size 3 had slightly dropped shoulders, and the body width had a comfortable amount of room.
