A vibrant 80s retro t-shirt design featuring a synthwave chicken sporting sleek aviator sunglasses, strutting confidently against a minimalist, neon-hued sunset. The background is a deep midnight blue, enhancing the chicken's luminous, fluorescent feathers that blend shades of electric pink, purple, and turquoise. Subtle grid lines crisscross the bottom, adding a touch of vintage futurism, while a soft retro glow envelops the scene, capturing the essence of nostalgic cool.
