Put to: A textile specialist and the cutter.
Why buyers should ask: Woolmark’s published fiber-quality specification bases Super S classification on mean wool-fiber diameter. Separately, VBC describes performance characteristics associated with yarn twist and fabric structure in its 21 Micron collection. These sources support asking about more than the Super number alone.

Draft answer framing: Ask the expert to start with the buyer’s real working conditions: outdoor exposure, office temperature, travel frequency, seated hours and tolerance for texture or creasing. Request an explanation of the trade-offs among weight, weave, yarn construction, lining and desired appearance.
Do not ask for one universal “best wool fabric weight for a business suit in a hot climate.” Ask for two or three suitable cloth references, why each was selected, and what compromise comes with each.
Press for: A written rationale tied to use—not an unsupported claim that a higher Super number means a better executive suit.
