Read the exclusions and the form of compensation. Nathan Tailors’ terms state that completed custom orders are not refundable. For identified workmanship or production errors reported with photographs within 30 days, the business reserves discretion to alter, remake or provide partial future credit; inaccurate customer measurements are excluded from its warranty.

As a US-facing comparison, Proper Cloth’s FAQ offers local alteration reimbursement of up to $125 for a suit as store credit, and describes remake and refund routes. That allowance is neither cash reimbursement nor evidence of the average cost of correcting an overseas suit. Confirm the conditions before relying on it. (propercloth.com)

Ask every candidate: Who diagnoses the problem? Must alterations be approved first? Is compensation cash or credit? Who pays both shipping legs? What happens if the first remedy fails?
