Ice and Snow Magical Girl Design

Create a full-body, front-facing design of an anime magical girl transformation costume against a clean white background, centered like a character concept art. The character is {argument name="character name" default="Ryuna"} A delicate, ice-themed magical girl with an incredibly ethereal {argument name="hair color" default="silver-white"} Long, soft, translucent hair, adorned with a large crystal snowflake hair accessory with a pale blue ribbon on one side. Her face is partially obscured by a simple, light-colored square placeholder, the rest rendered in an elegant, highly detailed pastel anime illustration style. She is dressed in gorgeous attire.{argument name="costume theme" default="White and ice-blue Snow Princess Magical Girl Dress"} The dress features an off-the-shoulder sweetheart neckline with lace trim, a fitted bodice, a crystal snowflake brooch, dangling blue gemstones, sheer puff sleeves, long white gloves, a choker made of frosty lace and jewels, and a layered, asymmetrical skirt. The skirt has multiple layers of semi-sheer ruffles, a shorter front and longer back hem, a long side train, a pale blue lining, shimmering snowflake patterns, crystal chains, star-shaped pendants, and teardrop-shaped gemstones dangling from the edges. It is paired with white knee-high stockings with delicate snowflake straps and dangling crystals, and elegant white high heels adorned with ice-blue snowflake embellishments. The pose is elegant and symmetrical, with arms slightly at your sides, hands outstretched, and legs together, as if floating during a transformation.{argument name="color palette" default="White, pearl, light ice blue, lavender shades, and clear crystal highlights"} The color scheme, combined with delicate lines, watercolor-like transparency, shimmering starlight, intricate lace, multi-faceted gemstones, and snowflake patterns, presents an ethereal and luminous texture.
