When evaluating lace, focus on the base material, which is typically 100% cotton (Swiss Voile), polyester, or organza. For premium markets, ensure the embroidery density is high with no visible gaps in the pattern. Check the GSM (Grams per Square Meter); a higher GSM usually indicates a more durable and luxurious feel. Additionally, verify the colorfastness rating (Grade 4 or above) to ensure the vibrant hues do not bleed during washing, and confirm the use of eco-friendly dyes compliant with international standards.
