TL;DR
Define the intended age group and use first, check real children's measurements for dressing and movement, inspect seams, attachments and packaging, and keep the sample records traceable.
Define intended age group and use first
Start by writing who the costume is for and how it will be used. Halloween costumes for kids are sold across a wide age range, and a design meant for a teenager is not the same product as one for a young child. Note the intended age group, the expected use such as a single evening event, and any accessories. This definition guides sampling and later checks, so it should be agreed before the first sample is made. Write this definition on the sample request so it travels with the style.
Confirm real measurements and fit for children
Ask for flat measurements and compare them with the age range you plan to sell. Children grow quickly between seasons, so a measurement table matters more than a size label. Note the recommended body range and confirm that the garment allows reasonable movement. Children's Halloween costume sizes vary by supplier, so record the measurements of the approved sample and keep them with the order. Where a style is offered in two fits, confirm which one the approved sample represents. Purchasing wholesale Halloween costumes for a store or a school event is easier when the size table is treated as part of the product rather than an afterthought.
Observe dressing, visibility and movement
Test the sample the way a child would wear it. Check how easily it goes on and comes off, whether the wearer can see and breathe comfortably through any mask or hood, and whether walking, sitting and reaching are possible. Note any point that snags, catches or restricts movement, and raise it before production rather than after. If a mask or hood limits vision, note it on the sample record so the point is not lost.
Check seams, attachments and packaging
Look at the details that affect durability and use. Confirm that seams are secure, that small parts are attached as intended, and that no loose piece could come free in normal wear. Check how the item is folded and packed, and whether the packaging carries the information you need. Seam and attachment checks matter most in kids Halloween costumes, where trims and small parts take more wear. Wholesale orders for Halloween costumes should record these points per style so a later reorder can be compared with the approved sample.
Keep sample records traceable
Keep one record per style: the sample version, its measurements, the person who checked it and the date. A traceable record makes a reorder easier and helps if a question comes up later. Store the approved sample and its documents together so the reference stays available. A photograph of the approved sample filed with the record makes identification quick at reorder time.
A short note on US children's product rules
Children's products sold in the US can fall under specific rules, and the requirements depend on the actual age group, product category, materials and intended use. Looking at a sample is not a compliance test. Certificates, testing and tracking labels should be confirmed by the importer with a qualified testing laboratory, and a single report does not automatically cover every style. Some products or materials are treated as exceptions, but an exception for one requirement does not remove the other obligations that may apply, so confirm the full set of rules for your item instead of assuming one rule covers the whole range. The links below are a starting point for checking the current requirements.
Kids sample checklist
