Approve a calendar with dependencies, not a promise measured only in days. Ask when cloth is available, when the responsible cutter is present and what happens if the first fitting requires another substantial adjustment.

Published supplier timelines are not uniform. SIR Tailor’s FAQ states a normal 21–30-day production period for a full-canvas jacket with available cloth and at least two fittings; it separately advertises a one-week expedited service under stated conditions. These are supplier statements, not verified delivery records or a universal minimum for Vietnamese bespoke tailoring. (sirtailor.com)

Complete this worksheet using actual dates and local appointment times:

Milestone Confirmed date/time Dependency If delayed, what happens?
Cloth and specification approved ___ Stock or procurement confirmation ___
Consultation and measurement ___ Buyer and technical staff availability ___
Intermediate fitting ___ Garment reaches agreed stage ___
Correction or additional fitting ___ Findings from earlier assessment ___
Final assessment ___ Alterations completed ___
Collection or dispatch ___ Acceptance and agreed payment milestone ___
US follow-up, if applicable ___ Named assessor and agreed scope ___

Choose a disruption to test—for example, a fitting moving by two days—and label it as a buyer-selected scenario, not an industry-average delay. If the plan then requires accepting unresolved faults at the airport, it fails the calendar check.

Do not assume that shipping after departure preserves the same service. Require the proposal to explain where any remaining assessment will occur and who pays if further work is necessary.
