Box pleats are a type of fabric fold commonly used in sewing and garment design. They are created by folding the fabric in alternating directions, forming a series of rectangular shapes that resemble boxes. This technique adds volume and structure to garments, making it popular in skirts, dresses, and curtains. Box pleats are often used in formal wear and uniforms, providing a polished appearance. They can also be found in home decor items like curtains and tablecloths. The pleats can vary in depth and spacing, allowing for customization in style and fit.
