A vibrant 80s-inspired t-shirt design featuring a synthwave chicken sporting an oversized pair of retro sunglasses, its feathers gleaming with neon hues. The chicken stands confidently against a backdrop of a minimalist, gradient sunset in shades of pink, orange, and purple, casting a soft glow. The scene is framed by subtle, swirling contour lines adding depth, set against a deep, star-speckled indigo sky that evokes a sense of nighttime adventure and nostalgia.
