A flat design for a skirt with a black background. The top layer features a wide, bold straight line stretching horizontally across the design, positioned distinctly at the top. The middle layer consists of only a few small blue butterflies, scattered very sparingly and placed clearly below the top line, adding a minimalist and delicate touch. The bottom layer includes flowing, simplified gold lines representing desert dunes, spread out with a bit more space, creating a sense of movement. Beneath this, a minimal gold line embroidery of a Chinese ancient earthen city wall, placed lower down with clean, simple lines to evoke traditional Chinese architecture. The overall design is clean, modern, minimalist, with well-separated elements and a refined contrast against the black backdrop.
