Finding opaque silk
Opaque is a constraint on silk, not a separate fibre. Confirm it on the fabric page after you filter.

Marketplace check
Silk is filed here as protein fibre. One reason to open it is distinctive surface character when well chosen. One reason to sample is care and abrasion resistance vary widely.
Judge opaque together with construction. Higher opacity can add weight or reduce breathability.
What not to assume
A opaque filter does not certify the cloth. dresses, blouses, scarves are common places buyers test silk, and some of those garments will reject this attribute.
Questions
- Does opaque silk mean every listing qualifies?
- No. Open the fabric page. If the spec does not support the attribute, drop the card.
