We have seen a gown quite exactly like this that was couture Oscar de la Renta for about $18K, and while the craftmanship of a de la Renta cannot be denied, brides on a budget will love love love this gown. We would pair it with navy satin platform stilletoes and a may-juh chunky cocktail bracelet with lots of crystals or, lucky girl, diamonds! Here is the official description:
Silk habotai with horizontal rows of crinkled silk chiffon. Strapless. Fitted bodice with silk organza interior corset for added support. Back zip. A-line skirt with a slight train. Fully lined in silk georgette. Falls to floor. Part of the J.Crew Collection. Import. Dry clean. Specially packaged in a custom-made box to ensure your gown is always as beautiful as the first day you wear it. Catalog/jcrew.com only.
