Convert the provided technical flat drawing into a colored technical fashion illustration. Apply a soft, feminine luxury color palette featuring blush pink, champagne beige, and ivory tones. Use clean, flat color fills to define different garment sections while preserving all construction details such as seams, stitching lines, darts, hems, panels, collars, cuffs, zippers, and pockets. Maintain a precise 2D technical flat style (no perspective), with consistent line work and accurate proportions. Ensure the front and back views remain clearly visible and aligned. Add subtle refined details such as light gold accents on hardware (zippers, buttons) to enhance the luxury aesthetic. Style: minimal, elegant, high-fashion technical illustration with a premium, polished look. Background: plain white. Avoid: shading, gradients, heavy textures, bold or busy patterns, 3D rendering, or artistic sketch effects.
