As a fan of online literature, I can't give a subjective evaluation because I can only answer questions based on what I have learned. However, according to the plot and character setting of Celestial Bane, the heavenly palace brocade dress (female) should be one of the most beautiful fashions. Bi Yao and Lu Xueqi were also wearing new clothes, but their designs and styles were slightly different. Therefore, the answer to which one was the most beautiful depended on one's aesthetic and preferences.
