Textile fiber waste in Pakistan is significantly produced; however, studies are needed to direct the reuse or recycling. This study demonstrated the preliminary market- based survey findings in the production of pre-consumer textile fiber waste, its collection, and the possible reuse in developing a new garment. Presently, this waste is mainly disposed of through burning or landfilling, creating an increased environmental footprint. This survey enhances the understanding of textile waste production for collecting, sorting and using in new garment making. The waste is collected from 35 commercial places in Karachi. Collected fabric pieces were used in the garment design by patchwork, and one case is demonstrated. The use of fiber dimensions, type, color, and variety found in the survey was demonstrated through a case study. It was found that the pre-consumer textile waste can be used in garment development through patch or applique designs. Several case studies were performed to apply waste fabric pieces in the design and development of fashion garments. Finally, one case study is demonstrated using patchwork to show the importance of waste fabric in garment making.
