The surplice style was invented to give the illusion of a more slender figure.. By virtue of the design alone, wearers can appear to look from 5-10 pounds lighter. The bodice is cut on the diagonal and crisscrosses over the bust. It has a sweetheart neckline and capped sleeves that barely cover the tops of the arms. This dress closes in back with a long, hidden zipper. The waistline is defined by a horizontal seam. The skirt portion is gently gathered and quite roomy for a full range of motion.
