To ensure the product meets luxury standards, focus on fabric composition (e.g., 100% mulberry silk, high-weight polyester, or heavy-duty lace). Pay close attention to stitching density, which should be at least 10-12 stitches per inch for durability. Verify the hardware quality (zippers like YKK, custom-engraved buttons) and the lining material, as high-end replicas use breathable fabrics rather than cheap synthetics. Additionally, request size charts with a tolerance of ±1cm to ensure fit accuracy for international markets.
