For its latest high fashion collab, L.A. denim kingpin J Brand has joined forces with international fashion label L'Agence to launch the CASHMERE JEAN. Opened in 2008, L'Agence is known to form the finest textiles, including washed silks and Japanese and Italian artisan fabrics, into modern yet classic silhouettes. Knowing that denim is a staple in every woman's wardrobe, the luxury label wanted to merge its philosophy with J Brand's focus on fit, resulting in this crafted cashmere denim piece. Just in time for the holidays, the elegant and cozy skinny silhouette comes in a blend of fine cotton and luxe cashmere, with a bit of stretch. The jean will retail for about $300 and is available at Barneys and Ron Herman.
