Silk or polyester: compare the actual article
A buyer seeking a particular handle may consider silk, while another prioritizes a repeatable care route or budget. Neither fiber name establishes the finished fabric's drape or durability. Compare composition, filament or yarn specification, weave, GSM, finish and sample behavior on the intended garment. Mark a fiber substitution as a deviation rather than an equivalent item.
Visual approval is not bulk performance approval
Approve the sample under agreed lighting and viewing direction, then identify the bulk lot that requires review. Satin float structure can make snagging or seam appearance relevant to selection; suitability depends on the exact construction and end use. A decorative swatch does not establish washable apparel performance.
