Create a detailed fashion illustration for a formal evening gown. The gown is a deep midnight blue with an elegant off-the-shoulder neckline and a fitted bodice. The dress has two design options: one side features a high-low layered skirt with delicate ruffle detail, while the other side features a flowing floor-length gown with intricate butterfly embroidery on the fabric. Both designs include sheer sleeves with layered ruffle detail, adding a romantic ethereal touch. The overall style is luxurious and enchanting, with a modern fantasy aesthetic. --ar 9:16 --v 6.1
