Futuristic Chrome Fashion Helmet

{argument name="aspect ratio" default="2:3 portrait"}, acid futurism fashion advertising photography. A model with a completely obscured face wears a complex but clearly structured experimental metal helmet, head turned three-quarters to the right, shoulders and chest naturally cropped from the bottom. The main subject occupies most of the frame, with clean blue negative space at the top and right. The helmet is a rounded mirror chrome dome, partially covered with titanium-blue coated perforated panels with neatly arranged small holes. Silver reinforcing ribs, fasteners, and connecting hinges are realistic and detailed. A short, sharp brushed silver visor extends from the front, above a single opaque curved iridescent face shield transitioning from electric blue and deep purple to pure orange and golden yellow, representing thin-film interference reflection rather than self-luminescence. Around the jaw are lightweight asymmetrical silver struts and a few white ceramic spherical nodes, showing clear mechanical connections without cluttering the main silhouette. The neck has a high collar made of clean pleated aluminized silver film, and the shoulder is a {argument name="fabric color" default="high-purity ultramarine blue"} glossy technical fabric with neat zippers and cut edges. The background is a uniform high-purity cobalt blue, slightly lighter only at the bottom. Strong directional sunlight and controlled white reflective surfaces form sharp, credible metal highlights, with deep black and transparent shadows, clearly reflecting the blue sky and white glossy surfaces. Extremely high detail, clean and dust-free, intense colors, and a sense of sophisticated industrial fashion in retro-futurism.
