To ensure a garment has enough room to move, which aspect must be considered?

When considering how to ensure a garment has enough room to move, ease is a critical aspect. Ease refers to the extra space allowed within a garment beyond the actual measurements of the body, which permits comfortable movement and flexibility. It is essential in any garment design as it directly affects how the garment will fit and function when worn. Without adequate ease, a garment may be too tight, restricting movement and comfort.

Fit, while related to how well a garment conforms to the body's shape, does not specifically address the additional movement space required. Style focuses on the aesthetic or design elements of the garment, while length pertains to the vertical measurements of the garment, neither of which specifically address the movement capacity needed in the overall design. In summary, when aiming for comfort and mobility in a garment, ease is the vital factor that must be incorporated into the design process.
