Quick answer: Custom swimwear costs $5–$12 per piece at wholesale for most bikini sets and one-pieces, plus $30–$80 per style per sampling round. Your real cost depends on order size, fabric, print, trims and the factory’s MOQ. A typical test launch of 100–150 pieces lands between $1,500 and $3,000 all-in.

1. The honest price range first
Prices below are typical FOB China figures in 2026 for mid-quality swimwear (nylon/spandex 80/20, standard trims, no special print complications):
| Product | 50 pcs | 100 pcs | 300 pcs | 500 pcs |
|---|---|---|---|---|
| Bikini set (2 pcs) | $9.50–12 | $7.50–9 | $6.50–7.80 | $6.00–7.00 |
| One-piece swimsuit | $9.00–11.50 | $7.00–8.50 | $6.20–7.40 | $5.80–6.70 |
| Rash vest / sun top | $8.00–10.50 | $6.20–7.80 | $5.50–6.80 | $5.20–6.20 |
| Boys’/men’s swim trunk | $7.50–10 | $5.80–7.40 | $5.20–6.40 | $4.90–5.90 |
Your exact price sits inside these ranges depending on the factors below.
2. What makes custom swimwear cost what it does
- Fabric: stock fabric is cheapest; custom-printed or recycled/GRS fabric adds 10–25%.
- Recycled fabric premium: ECONYL® / Repreve® typically adds +$1.50–$3.00 per piece vs standard nylon — the premium reflects GRS (Global Recycled Standard) certification costs and lower global recycled-yarn yield, not margin-padding.
- Print: solid color is cheapest; sublimation print adds $0.80–$2.50 per meter; complex placements cost more.
- Construction: lined pieces, cups, underwire, zippers and adjusters each add labor.
- Order size: fixed setup costs spread over more pieces = lower unit price (the biggest lever).
- Trims and branding: custom labels, hang tags and packaging are small per piece but add up.
3. Per-product cost breakdown (bikini / one-piece / rash vest)
Here is how a $7.80 bikini set (at 200 pcs) breaks down internally:
| Component | Share | Notes |
|---|---|---|
| Fabric + print | ~42% | Main cost driver; quality of nylon/spandex matters |
| Labor (cutting, sewing, finishing) | ~30% | Lining and cups push this up |
| Trims (elastics, hardware, cords) | ~12% | Metal hardware costs more than plastic |
| Labels, tags, packaging | ~8% | Small but always charged |
| Factory overhead + margin | ~8% | Covers QC, admin, utilities |
This is why “can you make it cheaper?” often comes down to fabric and order size, not labor.
4. Sampling costs: what to expect
- Standard sample: $30–$80 per style depending on complexity.
- Fit/PP sample before bulk: usually required for OEM, $30–$60.
- 2–3 rounds are normal before approval. Budget $100–$240 per style total.
- ODM and private-label styles often waive or heavily discount sampling.
What that fee actually covers: pattern making (flat pattern + grading across sizes), tech-pack checking against your spec, a small fabric cut, and one fit adjustment. Complex styles with cups, underwire or multi-piece construction run to the top of the range.
5. The 7 hidden costs buyers forget
- Tech pack / pattern development (if you don’t supply one)
- Shipping and freight — ask for FOB vs CIF vs DDP clearly
- Import duties and customs fees in your country
- Quality inspection (third-party or factory QC)
- Extra trims or linings not in the first quote
- Reprints or re-approval rounds
- Warehousing if your order arrives early/late
Budget 15–30% on top of the unit price to cover these safely.
Factory warning: custom digital-print setup typically runs $150–$300 per design, and freight + import duties can add 15–25% to landed cost. Always clarify in writing whether your quote is EXW, FOB, CIF or DDP before comparing suppliers. For US buyers, synthetic swimwear under HS Code 6112 carries around a 25.9% import duty — confirming the Incoterm is how you avoid a customs surprise.
6. Real budget examples: 100 pcs vs 500 pcs
| Item | 100 pcs bikini | 500 pcs bikini |
|---|---|---|
| Sampling (2 styles, 2 rounds) | $240 | $240 |
| Unit cost | $8.50 | $6.40 |
| Production subtotal | $850 | $3,200 |
| Labels, tags, packaging | $80 | $250 |
| QC inspection | $80 | $150 |
| Freight (sea/air mix) | $150 | $450 |
| Total | ~$1,400 | ~$4,290 |
| Cost per piece all-in | ~$14 | ~$8.60 |
Notice: ordering 5x more cuts your all-in cost per piece by ~38%. That’s the power of scale — and why testing small first is worth the higher per-piece cost.

7. 7 proven ways to lower your unit cost
- Increase order size — the single biggest lever.
- Limit colorways — 3 colors beat 6 at the same quantity.
- Use stock fabrics — skip custom prints for core styles.
- Simplify trims — plastic over metal hardware where possible.
- Combine styles into one shipment to save freight.
- Reuse patterns — build a “capsule” on 2–3 body shapes.
- Negotiate MOQ, not just price — a low-MOQ factory keeps you flexible.
8. How a low-MOQ factory changes the math
A factory that accepts 50 pcs per style (instead of 200+) lets you test a niche for a few hundred dollars instead of a few thousand. That means you can fail fast and cheap, then reorder your winners.
| Approach | Unit cost | First-order cash out | Inventory risk |
|---|---|---|---|
| High-MOQ factory (500 pcs) | Lowest ($6.00–$7.00) | $3,200+ tied up | High — dead stock if it doesn’t sell |
| Low-MOQ factory (50 pcs) | ~15–25% higher | ~$500–$700 | Low — test then reorder winners |
That’s the trade-off: a slightly higher unit price buys you dramatically lower risk. At YucaiFJ we run OEM from 50 pcs and ODM from 30 pcs, so even a brand starting with $2,000 can place a real order.

9. FAQ
How much does custom swimwear cost to produce?
$5–$12 per piece wholesale (FOB China), plus sampling; a small test line runs $1,500–$3,000.
Why is there a minimum order quantity?
Fixed setup costs (fabric batches, patterns, print files) must be spread over pieces.
What hidden costs should I budget for?
Shipping, duties, QC, extra trims and extra sampling rounds; add 15–30%.
How can I lower my custom swimwear cost?
Bigger orders, fewer colorways, stock fabric, simpler trims.
How much does it cost to start a swimwear brand?
$1,500–$3,000 for a first test line with a low-MOQ factory.
Why is sampling for custom swimwear expensive?
Each sample is essentially hand-made: pattern making, grading, tech-pack checking and one fit adjustment per style. $30–$80 covers that labour plus a small fabric cut.
What is the average margin for a custom swimwear brand?
Based on feedback from our 200+ DTC clients, most successful brands mark up landed manufacturing cost by 3.5×–4.5× to retail (a $7 landed cost supports roughly $26–$29 retail), which comfortably covers ads, platform fees and returns.
Can I reduce costs by supplying my own fabric?
Sometimes — you save the factory markup on fabric but must guarantee consistent quality, colour fastness and enough volume for your MOQ. Most brands find stock fabrics or factory-sourced recycled options more reliable.
How to Use This Guide
Use the ranges above as a planning tool, not a fixed quote. The fastest way to a reliable number is to send a complete brief — style, fabric, print, sizes, quantity per colorway and destination country — and ask the factory for a line-by-line breakdown. Comparing itemized quotes is the only fair way to judge which factory is actually cheaper.
