Design a Y2K-inspired Roblox classic shirt featuring a brown hoodie. The hoodie should have subtle vintage textures, a slightly oversized fit, and casual streetwear vibes. Include simple, stylized shading to emphasize folds and fabric details. Keep it suitable for Roblox’s classic shirt template, with no extra clutter or accessories, just the hoodie design in brown tones with a retro early-2000s aesthetic.
