A professional fashion visual board designed as a collage illustrating the life cycle of a fashion trend, using chunky sneakers (dad shoes) as the central example. The layout flows horizontally from left to right, showing five stages: introduction, rise, peak, decline, and obsolescence, without any rigid grid. On the left, include early runway looks and niche adopters with exaggerated chunky sneakers and experimental styling. Transition into influencer culture and street style, showing growing popularity through social media and celebrities. At the center, depict peak saturation with multiple sneaker brands, retail displays, and repeated bulky sneaker visuals, representing mass adoption and overexposure. Towards the right, show decline through cleaner, minimal sneaker styles replacing chunky forms, with softer silhouettes and neutral tones. On the far right, include refined and toned-down chunky sneakers, representing evolution into a seasonal trend. Use a color gradient from bold, high-contrast tones on the left to muted, minimal tones on the right. Include subtle lifestyle and retail elements to show cultural spread. Style: high-fashion editorial mood board, overlapping collage, soft shadows, depth, premium composition, minimal background, no text, no grid, ultra-realistic, 16:9 aspect ratio, fashion magazine quality, no watermark.
