RDenim fabrics.

MILAN — Tailoring and textile company Larusmiani will unfurl a new denim line called RDenim at the Denim Première Vision fair in Barcelona on May 18.

Larusmiani chief executive officer Guglielmo Miani told WWD that its RDenim line uses upscale yarns, rather than traditional indigo that is repeatedly dipped and oxidized.

“It means saving about 50 to 55 liters of water for every pair of jeans,” said Miani in an interview in Milan, near the store’s Via Montenapoleone showroom.

RDenim includes cotton blended with nylon, cashmere, wool, linen or silk to fit different seasons.

Larusmiani, which was founded in the Twenties by Miani’s grandfather, began experimenting with denim about two decades ago. In recent years, Larusmiani has become know for its upscale, easy Italian luxury fashions for men and women.

The family-run company, which makes its own yarns and fabrics, has been able to create yarns that are similar to traditional denim ones that through warp-faced twill weaving is blue on one side and white on the other.
