When sourcing designer-inspired or high-end women's apparel, focus on fabric composition and weight. High-quality garments should use natural fibers like silk, wool, or high-grade cotton blends rather than cheap synthetics. Inspect the stitching density (at least 10-12 stitches per inch) and ensure seam allowances are finished with overlocking or French seams to prevent fraying. For 'designer' categories, verify that the cut and draping align with professional patterns, as poor-fitting garments are the leading cause of returns in B2B fashion.
