When sourcing suit fabrics, the Super Count (e.g., Super 100s to 180s) is a primary indicator of fineness; higher numbers signify a softer, more luxurious feel, but may be less durable for daily wear. For commercial uniforms, prioritize wool-polyester blends (e.g., 70/30 or 50/50) to ensure wrinkle resistance and high rub counts (Martindale test >20,000 cycles). Always verify the fabric weight (GSM): 240-270g is ideal for all-season wear, while >300g is reserved for winter coatings. Additionally, check for colorfastness to dry cleaning (Grade 4-5) to prevent fading after professional maintenance.
