The lowest unit price often costs more because an FOB quote shows what a garment costs to make. It does not show what the garment costs to sell. Add freight, duty, inspection, defect recovery, customer returns and the markdowns that follow late or inconsistent stock, and the lowest quote can end up with the highest cost per unit sold at full price. Wadhsons has sourced and managed apparel production in China for 35+ years, with a specialism in denim. In denim, shrinkage, shade variation and wash consistency decide whether a style sells at full price or goes to the clearance rail. For that reason, this article compares quotes on total cost, not unit price.
About the Author: This article was written by the design and sourcing team at Wadhsons. Wadhsons is a Hong Kong-based supply chain partner founded in 1985 that designs, sources and manages apparel production for brands and retailers worldwide, with deep specialism in denim.
The total cost of quality is the cost of making a garment right plus the cost of everything that happens when it is made wrong. It changes the central question of this article. The useful figure is the cost of selling one garment at full price, not the cost of buying one.
| Cost bucket | What it covers in apparel | When you pay |
|---|---|---|
| Prevention | Tech packs, fit sessions, fabric testing, approved samples | Development |
| Appraisal | Inline and final inspections, lab tests | Production |
| Internal failure | Rework, re-dyeing, rejected fabric rolls, air freight to recover delays | Before shipment |
| External failure | Customer returns, chargebacks, markdowns, lost repeat customers | After delivery |
The two failure buckets make up the cost of poor quality. They rarely appear on a garment costing sheet. That is why a low quote can look better on paper than it performs in practice.
Building on that definition, a low unit price costs more when the saving comes from the visible buckets and the cost reappears in the invisible ones. Some quotes come in lower for legitimate reasons, such as efficient factory loading or simpler construction. The risk lies in quotes that depend on:
The mechanism works like a typo in a book. An editor can fix a typo in the manuscript in seconds. The same typo found after printing means a reprint. Apparel follows the same logic because every stage adds cost on top of the error. A shade mismatch caught at lab dip means re-dyeing a swatch. Caught in store, it wastes the fabric, cutting, sewing, washing, freight and shelf space already spent.
Competitive pricing usually reflects the quality of the problem being solved [note.com]. When a quote sits well below others for the same specification, ask which part of the problem is not being solved.
To move from why to how, use a quality-adjusted landed cost calculation. It adds expected failure costs to standard landed cost so you can compare quotes on equal terms.
Step 6 is where most quote comparisons change. Project costs move away from the approved budget when scope, assumptions, timing or prices change [ones.com]. A sourcing quote behaves the same way, because it is a budget that assumes on-time, on-spec delivery.
Once a defect reaches the shelf, returns and markdowns turn a quality problem into a margin problem. A return reverses a sale and adds handling cost. A markdown keeps the sale but gives away margin, and it is often triggered by late delivery or inconsistent sizing rather than weak design. A pricing strategy is ultimately a plan for how the business makes money [conta.com], so every unplanned markdown cuts directly into that plan.
Denim example: Suppose shrinkage differs between production lots. The same labelled size then fits differently, so shoppers order two sizes and return one. Reviews start to mention fit, and the remaining stock gets marked down. None of this shows up in the FOB price.
Consumers apply the same logic through cost per wear, which is the price paid divided by the number of times a garment is worn. Garments that hold their shape and colour earn a lower cost per wear, and they bring fewer returns and more repeat purchases.
A related but distinct question is whether paying more solves the problem. It does not. A 2023 study by the University of Leeds School of Design, commissioned by the environmental charity Hubbub, found that paying more for clothes does not necessarily mean they will last longer.
Price is therefore a poor guide to quality whether it is high or low. Quality comes from specification, fabric selection and control. The industry standard is AQL 2.5 for major defects and AQL 4.0 for minor defects, with zero tolerance for critical defects. AQL only samples what was produced, though. It cannot rescue a weak specification. This is why Wadhsons leads with its in-house design department. A well-engineered spec defines quality before the first metre of fabric is cut, and sourcing premium fabrics at reasonable prices means brands do not have to trade durability for margin.
[QUOTE REQUESTED: Wadhsons development lead on why denim quality is decided at the design and fabric stage rather than at final inspection]
Since price alone misleads, your supplier selection criteria should measure the factors that drive failure costs.
| Criterion | What to ask for | Cost it prevents |
|---|---|---|
| Development capability | Fit and sampling history, tech pack interpretation | Fit-related returns |
| Fabric sourcing depth | Mill relationships, test reports, shade control | Shade and shrinkage failures |
| Garment quality control | Inline and final inspection process, defect records | Rework and chargebacks |
| Compliance | Certified partners (for example Oeko-Tex, WRAP) | Reputational and audit risk |
| Delivery record | On-time history by season | Markdowns on late stock |
| Data transparency | Shared production tracking | Late warning of delays |
These criteria apply whether you are comparing China with Vietnam garment manufacturing or any other two markets. Origin affects duty and lead time. On its own, it does not determine quality.
Stepping back to the buyer’s operating model, an apparel sourcing agent lowers total cost by managing prevention and appraisal on the brand’s behalf. In end-to-end apparel supply chain management, one partner carries a style through design, sampling, production control, inspection and logistics, so quality responsibility does not get lost at hand-offs. Wadhsons works this way. It manages production at vetted partner factories, inspects at every stage from raw materials to final packing, and tracks production with data across the supply chain.
What is the cost of poor quality in apparel?
It is the combined cost of internal failures (rework, rejects, recovery freight) and external failures (returns, chargebacks, markdowns).
How do I compare two quotes fairly?
Calculate landed cost plus expected failure costs for each quote, then divide by the units you expect to sell at full price.
What should a garment costing sheet include?
It should cover fabric, trims, cut-make-trim, finishing, packaging and margin. Use it as the base for a landed cost calculation, not as the final figure.
Is AQL inspection enough?
No. AQL samples finished goods. Specification, fabric testing and inline checks stop defects before they are made.
Does sourcing location affect total cost?
Yes. Location affects duty, freight and lead time. Supplier capability matters more for failure costs.
Why is denim especially sensitive to total cost?
Shrinkage, shade variation and wash consistency affect fit and appearance directly, so small production variances quickly lead to returns.
