Onsen

Explore Onsen Cotton Loungewear Online

Onsen is a women's loungewear collection made entirely from 100% cotton, spanning tops,  button-downs, bottoms, robes, and casual dresses. Each piece is cut for softness and airflow, so the fabric breathes against the skin and grows softer with every wash. The result is a coordinated set of relaxed, easy-to-wear essentials for time at home and low-key days out.

Because everything is designed as separates, you can build a set around your routine, pair a tank with bottoms for time at home, or reach for the caftan dress when you want a one-and-done look. It sits within Natori's broader cotton clothing collection, made from the same natural, breathable fiber.

From Lounge to Errands: Cotton That Goes Anywhere

Cotton loungewear no longer stops at the front door. Breathable and easy to move in, these pieces suit a day spent switching between the desk, the sofa, and a quick errand, comfortable enough to relax in, pulled-together enough to answer the door or step out. If this collection suits your style, discover Natori's Sleep to Street edit follows the same idea across other fabrics and styles.

How do I care for my cotton loungewear?

Machine wash cotton in cold water on a gentle cycle and tumble dry low or lay flat to help preserve the fit and reduce shrinkage. Washing inside out helps protect the fabric surface over time, and it's always worth checking the care label on each piece. Learn more in our sleep and lounge product care guide online.
