What this score doesn't measure
This is a material rating, not a verdict on any specific garment made from mulberry silk. The axes above are research-backed averages for the fiber itself.
- ×Construction. Yarn staple length, weave / knit structure, stitch count, finishing. Identical fiber, very different garments.
- ×Fabric weight (GSM). A 140 GSM tee and a 220 GSM tee made of the same mulberry silk feel and last very differently.
- ×Dye + finishing chemicals. Beyond the three we flag (PFAS, formaldehyde, antimony), dozens of textile finishes aren't modelled.

Special Notes
• Highest quality silk — handle with extra care
• Use a mesh bag if machine washing on delicate
Additional Care Tips
- • Dry clean only for garments — specify silk-safe solvent to cleaner
- • If hand washing, use cool water (below 30°C) with silk-specific detergent only
- • Never wring, twist, or rub — blot gently with a towel to remove water
- • Air dry flat on a towel away from sunlight — UV causes yellowing
- • Iron inside out on the lowest setting with no steam, or use a press cloth
- • Store in breathable garment bags on padded hangers; avoid plastic which traps moisture
