Only a complete comparison can answer that. Calculate the cost of obtaining an acceptable suit, not just the amount paid to the overseas workshop.

Use:

Delivered cash cost = garment + separate fitting fees + shipping + import charges + payment/FX costs + local alterations + incremental travel.

Include applicable domestic taxes in the comparison where relevant. Keep executive time separate from cash expenditure. Import charges should remain unresolved until supported by an entry-specific estimate; the USITC's current tariff resources are the starting point, not a generic country percentage. (usitc.gov)

An illustrative comparison—not a quotation or forecast

Cost item Illustrative amount
Vietnamese garment $1,200
Separate fitting fee $100
Shipping $80
Payment/FX costs $30
Planned local alteration allowance $150
Extra travel attributable to the commission $200
Subtotal before import charges $1,760
Comparable US all-in option $2,200

Let I be actual import-related charges and C be additional correction spending beyond the $150 already allowed.

Remaining cash advantage = $440 − I − C.

The overseas option loses its cash advantage when I + C exceeds $440. No probability is assigned to that outcome.

Do not charge an entire pre-existing business trip to the suit. Do include extra nights, flights or journeys caused by fittings. Record appointment and administration hours separately so a modest cash saving does not conceal an unacceptable time commitment.
