"Create a high-quality black beanie for Roblox UGC with a realistic knitted fabric texture. Show clear woven fibers, subtle ribbing, and detailed stitching along the edges. The beanie should look soft and slightly elastic, with natural folds and shadow depth. Keep the color pure black but with controlled highlights that reveal the texture without losing detail. Use clean studio lighting, a centered product view, and no background. The design must appear polished, professional, and UGC-ready.
