Evaluate the pattern, fitting process and internal construction separately. The Savile Row Bespoke Association describes an individually handmade pattern cut by a master cutter. Suitsupply’s Custom Made service separately offers a choice of full- or half-canvas construction. Our conclusion: a canvas specification alone cannot establish an individual-pattern, fitting-led process. The association’s description is a craft benchmark, not certification of a Vietnamese supplier. (savilerowbespoke.com)
Ask for the process applying to your quoted service, rather than accepting a general description covering several product tiers.
