Polo shirt. Pierre Cardin Paul shirt is a Polo shirt, which has both the gentleman feeling of the shirt and the cool feeling of the T-shirt, and can be switched between formal and casual. The tall and straight collar will not look too casual when worn on the upper body, nor will it be as deliberate as a shirt, but it will look particularly energetic. Pierre Cardin originated in Paris, France, and belongs to Jiansheng Lubao International Holding Co., Ltd., which is a brand of men's and women's shoes that combines the exquisite traditional craftsmanship and cultural heritage of France with the modern fashion culture of China.
