This piece is part of the COS ATELIER collection, a limited capsule founded on the principles of luxury and exceptional design. ​​CUT ​The ATELIER backless vest lends itself beautifully to layering but looks equally striking worn solo. It has been expertly tailored for a classic cut and has a cinched waist, a low cowl back supported by an elasticated band and a slender halterneck in lieu of traditional shoulder straps. Our stylists suggest wearing it as a three-piece suit with the deconstructed blazer and pants from the collection. CLOTH​Chosen for its substantial hand feel and effortless drape, the weighty stretch-crepe cloth is enhanced with a touch of premium Mulberry silk. It fastens with a row of color-matched corozo buttons. CRAFT​Every detail has been carefully considered, from the clean edges to the tonal topstitching. 78% Viscose, 18% Mulberry silk, 4% Elastane / Dry clean Front length of size 6 is 19.48" / Model wears a size 6
