Curvy shapes are characterized by smooth, flowing lines that create a sense of softness and roundness. These shapes can be found in nature, such as in the form of hills, waves, or the contours of a human body. Curvy shapes often evoke feelings of comfort and warmth, making them popular in design and art. In geometry, curvy shapes include circles, ellipses, and various types of curves. Unlike straight lines or sharp angles, curvy shapes can create dynamic and visually appealing compositions. They are often used in architecture and product design to enhance aesthetics and improve functionality, as seen in items like furniture and automobiles.
