This underwear sampling lead time guide explains the 5–7 day sample guidance for DIYASI catalogue styles. Confirm the start after the team checks the model, materials, artwork and changes. Sample preparation, your approval, courier delivery and bulk production are separate milestones. A dispatch plan must be confirmed for the actual brief; do not treat the sample guidance as a guaranteed arrival date.
How to request underwear samples from factory
Send model numbers, sample size, selected colors, intended market and the reason for the sample. Say whether you need a base garment for fit review or a branded garment with packaging. Attach artwork and mark every change to fabric, fit or components. Missing decisions need clarification before a meaningful schedule can be agreed.
OEM underwear sampling 5-7 days: define the start
Ask the team to acknowledge the approved sample brief and confirm material availability and the planned sample completion point. Keep the quotation and shipping arrangement together with that acknowledgment. Revised artwork, unavailable components or pattern changes need a revised plan, rather than an invented second sample duration.
| Milestone | Confirmation needed |
|---|---|
| Brief review | Selected model, materials, artwork and changes |
| Sample preparation | 5–7 day guidance; agreed start and completion plan |
| Buyer approval | Fit review, measurement record and revisions |
| Courier dispatch | Destination, shipping method and documents |
| Bulk planning | Approved sample, quantity, packing and written schedule |
Sample review: compare garment and brief
Measure the sample using the agreed points, then inspect body and gusset composition, coverage, seam placement and waistband. For DYS323, review the bonded cotton gusset and cut edges; for M005, review the modal pouch separately from the polyester/spandex body. Photographs can support the record but should not replace a physical fit assessment.
Underwear manufacturing cost breakdown for samples
Request sample fees, development or artwork charges, packaging and courier costs in the actual quotation. Confirm any fee credit against a later bulk order in writing. Keep the approved sample, dated revision list and final component files so a subsequent production quote is based on the version you really approved.
One more thing
Does 5–7 days include shipping?
It is sample-preparation guidance. Confirm completion, dispatch, courier delivery and customs separately for your destination.
What happens if I change the pattern or artwork?
Ask the team to review the revised brief and confirm a new plan. This guide does not promise a separate fixed duration for changed patterns, colors or components.
Do I need to approve a new sample after changes?
Agree the approval scope with the team. A change to fit, material, waistband or labeling may require a revised physical reference before bulk production.
