Cotton Linen Dungaree Ocean Short Sleeve Shirt

With a relaxed fit through the body and a slightly shorter length, the Ocean Shirt offers a silhouette that feels easy yet never looks sloppy—even when worn oversized. Named after the idea of “infinite expansion,” this piece invites you to explore endless styling possibilities.

The fabric is a refined dungaree, woven from a blend of flax-colored linen and deep indigo blue—perfectly suited to the sea breeze. The linen used here is of exceptional quality, now increasingly rare, and when woven together, it brings both structure and a gentle volume. The texture is dry and tactile, with a summery grain that feels refreshing against the skin.

Inspired by Ruri, the Japanese name for lapis lazuli, this shirt captures the luminous clarity of that precious blue stone. When the light hits it, the indigo takes on a vivid brilliance. With repeated wear and washing, the fabric gradually softens, deepening in character and comfort. It is a quiet celebration of Japanese craftsmanship, as expressed through 45R’s thoughtful approach to design.
