Hydrangea Yunomi | No. 431Youth T-Shirt

Structural Specifications: The Youth Form (Build 3001Y)

The ichinichi discipline is not bound by scale. Build 3001Y translates our uncompromising standard to the miniature form. Engineered to deliver the exact same structural drape and tactile endurance as our master archive, this artifact provides a clean, continuous line designed to withstand high kinetic energy without losing its architectural shape.

The construction remains rigorous. It features strict side-seamed execution, a classic genderless proportion, and a frictionless interior to ensure the garment moves seamlessly with the wearer. We do not dilute the quality for scaled proportions; this is pure, uncompromised utility.

Material Architecture: Solid artifacts are forged entirely from 100% Airlume combed, ring-spun cotton. The Ash variant introduces a highly deliberate 99/1 cotton-poly integration. Operating with a refined 32-single thread count and a pre-shrunk fabrication, the textile yields an exceptionally dense, premium finish that endures the daily cycle.

Available across scaled parameters (YS–YXL), serving as the essential foundational layer for the next generation's daily rotation.

Every ichinichi piece is made on demand, only after it is ordered. This keeps us out of the cycle of excess inventory and unnecessary waste.

Your garment is produced specifically for you, with a typical 3–4 day fabrication period before shipping. It is a slower, more deliberate model, but one that lets us make only what is needed and keep the process focused on quality rather than volume.

Nothing is pulled from a stockpile. Your piece is made for your daily rotation when you commission it.

ichinichi ships worldwide, with complimentary shipping on every order.

To reduce unnecessary transit and support our on-demand model, we work with a decentralized production network across the US, EU, UK, and Japan. Whenever possible, your piece is produced at the facility closest to your destination.

After a typical 2–5 day fabrication period, most orders arrive within 3–6 days, depending on region. Delivery times may vary internationally, but each order is routed through the nearest available production hub.
