Build a chain of evidence from specification to cloth selection to the individual commission. Do not award full provenance points solely for a sewn-in label, a photograph of a branded book or the supplier naming a famous mill.
Request:
- Maker or merchant and collection name.
- Exact article and color reference.
- Fiber composition and weight, preserving the source’s units.
- Confirmation that sufficient cloth is available for the agreed order.
- A retained swatch or other agreed reference linked to the order.
- Proportionate procurement evidence where provenance is a material buying condition; commercially sensitive prices may be redacted.
- Written approval before any substitution.
Mill information is a useful cross-check. For example, Vitale Barberis Canonico describes Perennial as a business-suiting cloth in Super 110’s merino wool at a stated weight of 260 grams. That helps test whether a quoted description is consistent with the collection; it does not prove which cloth a tailor actually used. (vitalebarberiscanonico.com)
For construction, ask the tailor to specify the canvas coverage, any fusible reinforcement, lining and agreed finishing work. Request relevant in-process evidence tied to the order where practical. Under this rubric, a pinch test or exterior photograph alone does not earn a verified hidden-construction score.
For a US-facing business sale, the FTC’s textile guidance identifies fiber content, country of origin and responsible-business identity as core labeling information for most covered products. Treat labeling as part of documentation and compliance—not as independent authentication of a premium mill claim. (ftc.gov)
Do not prescribe one universal fabric weight for every executive. Ask the cutter to explain the choice against the buyer’s actual climate, indoor conditions, travel, desired appearance and wear frequency. Record that rationale rather than awarding points for a high Super number or a prestigious name.
