Create a fashion illustration of a dog in the style of bold graphic illustrations, posing confidently for the camera. The illustration should feature colorful shapes and curves in vibrant orange, pink, purple, and yellow colors, inspired by pop art and classic fashion illustration. Incorporate bold color blocks and black lines to define the dog's form and enhance the graphic quality of the design. The dog should be stylized with exaggerated features and a playful expression, capturing its personality and charm. Position the dog centrally in the composition, ensuring it is the focal point, while using dynamic shapes around it to create a lively and engaging visual experience. The overall atmosphere should be playful and vibrant, inviting the viewer to appreciate the joyful essence of the illustration.
