Create a vector illustration in a pop-art style inspired by Nishio Inoue, featuring a soft and elegant woman. She is dressed in an elegant pantsuit that is both sophisticated and noble. The illustration should have a bright color palette and colorful aesthetic, with the woman exuding a gentle and graceful demeanor. Her outfit is a stylish, tailored pantsuit in luxurious fabric, and her appearance is soft yet confident. She has a warm, approachable smile and is accessorized with minimal but high-quality jewelry. The overall image should combine the softness of her personality with the bold, vibrant colors of the pop-art style.
