Light blue cheongsam top with black skirt, soft gradient background AI Image Prompt

Change the character's clothing to a light blue cheongsam short-sleeved top, retaining the mandarin collar, frog buttons, delicate light gold patterns, and slight satin texture; change the lower garment to a black high-waist skirt with hem at mid-thigh, simple and clean silhouette. Replace the background with a soft gradient from light blue-gray to off-white, with very faint Chinese window pane patterns and a subtle glow. The overall look should be clean and sophisticated, with ample space for adding personal text later. Maintain natural and harmonious posture, hairstyle, and body proportions.
