Hanro Response: This gown is tailored from mercerized cotton interlock, which makes the fabric thicker and more opaque. The top-stitched seams are designed to provide a sleek, flattering silhouette. You may prefer Champagne Tank Gown style 76473. Although this is a single jersey knit, it is tailored from a luxurious blend of viscose and elastane for opaqueness and stretch. Sam from St. Louis
