A vibrant 80s retro t-shirt design featuring a synth wave chicken sporting sleek sunglasses, set against a minimalist sunset with neon pink and orange hues. The chicken exudes a cool, confident vibe, with its feathers highlighted in electric blues and purples. The background is a deep midnight blue, accentuating the sun's radiant glow, and a subtle grid pattern enhances the retro aesthetic. The overall design is framed in a bold yellow contour, providing a striking contrast to the dark backdrop.
