Use the person in the uploaded selfie as a model, preserving their posture, expression, and background tone. Replacing clothing for the character: It is necessary to use the exact same color as the character's clothing in the original photo, and choose a design that is similar to the original but has the Calvin Klein brand's iconic style - highlighting a simple and clean cut, incorporating the brand's classic letter logo elements (which can be reflected in the collar, cuffs, or appropriate positions on the body), and the fabric is biased towards comfortable and breathable cotton or slightly elastic materials, presenting CK brand's unique modern, sexy, and casual fashion sense as a whole. The final generated advertisement image features a full body image with coordinated light and shadow, natural color transitions, and clear and distinguishable clothing details. It preserves the original characteristics of the characters while highlighting Calvin Klein's brand tone
