Waist line plays a very important role in dressing. Maybe you don't know it in your heart, but just look at two different suits of the same person from the same angle in the picture below. Because of the embellishment of the waistline, the shape on the right side makes the waist look thinner and the legs are much longer visually. Shoes and trousers are the same color, so keep the same color. To some extent, it can be seen that shoes and pants are connected, and shoes naturally become an extension of pants, making your legs look longer visually.
