A vintage 80s retro t-shirt design featuring a neon-colored synth wave chicken sporting sleek sunglasses, standing confidently against a minimalist sunset with hues of pink and orange. The sunset is set over a grid-patterned horizon, casting reflections that enhance its vibrant glow. The chicken's feathers have a subtle shimmering effect, adding depth and style. The dark background elevates the scene, with faint outlines of distant palm trees to capture the essence of an 80s coastal vibe.
