TL;DR
Verify legal identity and the production site, match technical capability to your range, insist on garment samples and a written specification, then compare offers on identical commercial fields before agreeing changes and inspection.
Start with the role the supplier actually plays
A trading company, an agent and a factory can all quote a costume, but they answer for different things. A producer controls cutting, sewing and finishing in house, so specification changes and defect decisions happen at the source. A trader coordinates several producers, which can be useful for a mixed assortment, yet the technical answer usually comes from someone else. Ask directly which party holds the production site, who signs the sample and who handles a defect claim.
Shanghai Haitailu Clothing Co., Ltd works as an OEM and ODM producer from Shanghai, and its catalogue at www.festivocostumes.com lists styles by series and item number. Buyers can reference an existing style or send artwork for a new one, and either path starts from a written brief rather than a catalogue photo alone.
Confirm legal identity and the production address
Ask for the registered company name, the business registration number and the city where garments are actually made. A quote without a verifiable address is difficult to audit and harder to escalate if something goes wrong. Cross check that the name on the invoice, the name on the sample paperwork and the name on the shipping documents match.
Photographs of a workshop are useful but not sufficient. A short video call walking through the cutting table, the sewing line and the packing area tells you more about organisation than a picture of a showroom.
Match technical capability to your range
Costume production is not one skill. A factory that sews simple knit garments may not handle structured bodices, layered tulle skirts or printed panelling. Describe your range in technical terms: fabric type, number of components, closures, embellishment and expected packing. Then ask which of those the line handles routinely and which would be subcontracted.
If a style needs printing, embroidery or a specific trim, ask where that step happens and how the component returns to the main line. Subcontracted steps are normal, but the handover points are where delays and colour mismatches appear.
Ask for garment evidence, not catalogue images
Request a physical sample of comparable work, or at minimum a sample of the exact style you are considering. Check seam finishing, hem alignment, closure function, trim attachment and the inside of the garment. A costume that photographs well can still have loose thread ends, skipped stitches or a zip that catches.
Keep the approved sample and record its date. Every later question about colour, length or trim placement can then be answered against one reference instead of a description.
Compare offers on the same fields
Minimum order quantity, unit price, sample cost, lead time and packing are quoted per project, so treat each figure as an assumption until the supplier explains the basis. Ask whether a price covers all sizes in the run, whether accessories and hangers are included, and what happens to cost if the size split changes.
Line up the offers with identical columns and note what each one leaves out. A quote that already includes labelling, polybags and carton marks is easier to plan than a lower figure with open items that reappear later.
Agree how changes and inspection will work
Before production, put measurements, materials, trims, size grading and packing in writing, and name the person who can approve a change. Agree the inspection point, what the inspection checks, and how a defect is corrected or credited. Manufacturers that answer these questions with a process rather than a promise are easier to work with over repeat seasons.
Buyers who want to see the range before starting a program can browse the catalogue and request item numbers through the contact page on www.festivocostumes.com.
