A vibrant 80s-inspired retro t-shirt design featuring a cool synth wave chicken wearing sleek aviator sunglasses. The chicken is positioned against a minimalist sunset, with its vivid hues of orange and pink cast in smooth gradients across the sky. The background is a deep, rich midnight blue, enhancing the contrast and the retro aesthetic. The chicken, detailed with bold geometric lines and subtle neon accents, exudes a sense of laid-back style. This nostalgic yet futuristic design is accented with palm trees silhouetted along the horizon, evoking a classic Miami Vice vibe.
