Indigo Cotton Fleece Denim Puff Sleeve T-shirt

A puff-sleeve T-shirt with gentle volume at the cuffs, this top gives the layered look in a single piece—an easy way to complete an outfit with balance and style.

The reverse fleece, knitted with a two-stitch skip technique, has the rugged appearance of heavy-ounce denim, yet feels as soft as gauze against the skin. Its relaxed texture, denim paneling, and subtly faded discharge print evoke the charm of a vintage sweatshirt lovingly remade.

For the flared section, we used Mon Petit denim—a lightweight fabric with a clearly defined weave, where the white of the weft yarn subtly brightens the design. This thoughtful blend of materials reflects the understated artistry of Japanese craftsmanship, a hallmark of 45R.
