45 Petit Denim Puff Sleeve Blouse (Size 3)

A back bridge detail spans the rear opening, while gently gathered shoulders give the sleeves a soft puff—charming touches that evoke a playful, feminine spirit. The hem can be cinched with a tie for a compact and sweet silhouette, making this blouse a quietly expressive piece.

The 45 (Yoi) Petit Denim is a left-hand twill denim—a fabric we haven't woven in quite some time. This special material reflects 20 years of accumulated knowledge, refined and deepened through experience. It embodies the thoughtful craftsmanship that defines 45R and its Japanese roots.

When left-twisted yarns are woven into a left-hand twill, the threads tighten firmly, resulting in a fabric with a clean, structured surface. Naturally prone to developing character, this denim reveals new expressions over time through repeated wear and washing. It’s finished in a rich, one-wash indigo that offers a quietly striking depth.
