45 Petit Denim Puff Sleeve Dress

This dress has a soft, girlish charm, with gently gathered shoulders that give the sleeves a rounded puff, and a back bridge where fabric spans the open panel. It’s a silhouette that feels both lighthearted and considered.

The 45 (Yoi) Petit Denim is a left-hand twill denim—one we haven't produced in quite some time. Woven from the knowledge we've cultivated over 20 years, it represents a deepened expression of 45R's Japanese craftsmanship.

By using left-twisted yarns and weaving them into a left-hand twill, the threads tighten firmly, creating a distinct and structured surface. This denim is especially prone to developing character with each wear and wash, gradually revealing unique expressions. Finished in a deep indigo one-wash, it carries a quiet strength and the promise of graceful aging.
