The fabric utilized for test fitting is identified as Muslin. Muslin is a cost-effective, plain-woven cotton material. Its lightweight nature, ease of sewing, and affordability make it perfectly suited for the creation of prototype garments, also known as toiles or test garments. The use of muslin enables designers to verify the fit, style, and design of a pattern prior to cutting the final fabric. Any necessary modifications can be implemented on the muslin prototype, thereby avoiding the risk of damaging costly materials. Consequently, muslin fabric is the favored selection for test fitting due to its economical price point and practical usability.
