Your second skin. An illusion design where tulle and floral appliqués in thread embroidery blend into the neckline and long sleeves creating a tattoo effect. The back neckline and mermaid skirt ending in a train, streamline the figure and accentuate the sensuality of your shape. Furthermore, gemstone appliqués provides light and make the design sparkle with its own light.
