Fit customization is a feature that allows customers to tailor a product’s size and measurements to their exact body dimensions instead of relying only on standard sizes like S, M, or L. It gives buyers the option to provide specific details such as chest, waist, hips, sleeve length, or inseam, and can also include alterations like adjusting sleeve length, pant hem, or selecting different fit types such as slim, regular, or relaxed. For apparel and uniforms, it may also involve adding personalized touches like embroidered names or printed logos. This customization not only ensures a better and more comfortable fit but also reduces the chances of returns or exchanges due to sizing issues.
