When sourcing luxury clothing, the fabric composition is the primary indicator of value. Prioritize natural fibers such as Grade A Mulberry silk, 100% Mongolian cashmere, or high-thread-count Egyptian cotton. For craftsmanship, inspect the stitch density (typically 12-15 stitches per inch), the use of French seams for clean interior finishes, and the alignment of patterns (like checks or florals) at the seams. Ensure that hardware, such as YKK zippers or real mother-of-pearl buttons, is used to reflect the premium positioning of the garment.
