Private label kids swimwear sounds simple: pick a swimsuit, add your logo, sell it under your brand. In practice, the brands that launch on time are the ones that understand the sequence before they start. Every step depends on the one before it — a print approved late delays the sample, a sample approved late delays bulk fabric booking, and a bulk order booked late misses the season.
This guide walks through the process the way a factory sees it, from first enquiry to first shipment, so you can plan your launch backwards from the date your customers need stock.
Step 1: Define the range before you contact a factory
Start with decisions only you can make: who is the range for, and what does it need to do? A baby swimwear line for swim schools has different requirements from a girls' fashion range for boutiques — different fits, different coverage, different price points. Decide the age range, the styles (one-piece, bikini, tankini, rash guard set, swim diaper), and the number of styles you can realistically launch. Most new brands do well with four to eight styles: enough to look like a collection, few enough to manage sampling and stock.
Then set a target price and a realistic first quantity. Our minimum order is 100 pieces per style per colour, which lets a new brand test a style without committing to thousands of units. Share your target price honestly at this stage: a factory can tell you immediately whether your fabric and trim choices fit it, and suggest alternatives if they do not.
Step 2: Get a quotation you can compare
Send the factory your style references, sizes, colours and quantities, and ask for a formal quotation with the full breakdown: fabric, trims, labels, packaging, sampling cost and lead time. A quotation that only shows a unit price is not enough — you need to know what is included and what is extra, so you are comparing like with like across factories.
We reply with a formal quotation within 24 hours on working days. At this stage, also confirm the factory's credentials: our Quanzhou factory was founded in 2013, covers 4,000 m² with 100+ workers and a monthly capacity of 80,000+ pieces, and holds SGS, BSCI, GRS and OEKO-TEX certifications. Those details matter most when your retail customers ask for them later.
Step 3: Develop prints, colours and labels
Private label means the product carries your identity, not the factory's. That identity has four parts, and each needs approval before sampling:
- Prints and colours: your own artwork, or a factory print adapted in your colourway. All-over prints are confirmed with strike-offs — small printed fabric swatches — so you see the real colours before cutting.
- Labels: your woven neck label, size label and care label, with the wording your market requires.
- Hangtags and packaging: your hangtag, polybag and any retail packaging. Packaging is often forgotten until the end; decide it now, because it affects the quotation.
- Fabric: the hand feel, stretch and weight you want. If you need UPF 50+ claims, confirm at this stage that the fabric is rated and that test reports can be provided with bulk orders.
Browse our existing girls swimwear and baby swimwear ranges to see the style families that adapt most easily to a private label programme — one-pieces, bikinis, tankinis, long-sleeve sunsuits and rash guard sets.
Step 4: Approve the sample — and check more than the look
Sampling takes 7–10 days. When the sample arrives, check it the way your customers will: fit on a real child in the right size, stretch and recovery after pulling, stitching at stress points (straps, leg openings, zips), print colour against your approved strike-off, and label placement. Photograph any changes clearly and mark them on the sample — a marked sample with notes is faster to revise than a long email describing a fit problem.
Most styles need one or two rounds of sampling. Budget for that in your timeline rather than assuming the first sample is final. A factory that rushes you past sampling is saving itself time at your expense.
Step 5: Confirm bulk production and the timeline
Once the sample is approved, bulk production takes 25–40 days depending on quantity and fabric availability. Confirm four things in writing before production starts: the final approved sample as the bulk standard, the size breakdown, the delivery date, and the quality standard. Our bulk inspection standard is AQL 2.5, and we recommend agreeing the inspection method — factory self-inspection, your third-party inspector, or both — before the order, not after a problem appears.
Plan backwards from your selling season. If you need stock in stores for a summer launch, allow sampling time, two sample rounds if needed, bulk production, inspection and shipping. Brands that miss a season almost always lost the time in steps 3 and 4, not in the factory's production schedule.
Step 6: Inspect, ship and learn from the first order
Before shipment, check the bulk against the approved sample: fabric, colour, print, fit, labels and packaging. Note anything to improve for the second order — a fit tweak, a stronger elastic, a different colour split. The first order is a test of the whole system, not just the product: your best second order is built on what the first one taught you about sizes that sold, colours that moved and quantities that were right.
That is also the moment to decide what the brand does next: repeat the best sellers, drop the slow styles, and add one or two new styles for the next season. Private label works as a programme, not a single purchase.
The mistakes that cost new brands most
- Starting with the logo instead of the range. A logo on a style nobody wants is still a style nobody wants.
- Approving a print from a screen. Screens lie about colour. Always approve a physical strike-off.
- Ordering one size run without a size curve. Decide the size breakdown from your market's sizing, not by splitting quantities evenly.
- Leaving packaging until after production. Packaging lead time is real, and it can hold up an otherwise finished order.
