Develop a First DTC Period Underwear Collection
Develop a First DTC Period Underwear Collection. Brand owners, channel operators and sourcing teams
Written for brand owners, channel operators and sourcing teams, this working brief turns the key questions around first-assortment width, non-negotiable specifications, sampling budget and launch gates into a dated brief, a comparable quotation and a controlled next step.
Limit the first assortment
A first DTC collection should be narrow enough to validate fit, absorbency, packaging and replenishment. Start with the styles, sizes and colourways that support the launch story rather than a full catalogue.
Prioritise non-negotiable specifications
Write the non-negotiable specifications before sampling: gusset coverage, absorbency target, skin-contact material, care route, size model and packaging format. Everything else can remain a development option.
Development and testing budget categories
Budget development, samples, testing, artwork, photography and reorders separately. A low unit price can hide costs that appear only after the first sample or after the channel requests more evidence.
Approval gates before purchase order
Use approval gates for fit, materials, test status, artwork and purchase order. Each gate should identify the approver, evidence and open issue so the launch date is not based on verbal readiness.
Launch-readiness handover
Hand over the approved sample, BOM, size set, artwork, test file and reorder assumptions to operations. A launch is ready when the next production run can use the same controlled baseline.
Decision register
| Stage | What to record | Minimum evidence | Dependency |
|---|---|---|---|
| Limit the first assortment | Decision, reference and version | approved brief and scope note | BOM, material and certificate scope, development parameters and approvals, commercial terms and packaging |
| Prioritise non-negotiable specifications | Decision, reference and version | dated specification, BOM or official-source note | BOM, material and certificate scope, development parameters and approvals, commercial terms and packaging |
| Development and testing budget categories | Decision, reference and version | sample, test or registration record for the named reference | BOM, material and certificate scope, development parameters and approvals, commercial terms and packaging |
| Approval gates before purchase order | Decision, reference and version | named approval, exception and change log | BOM, material and certificate scope, development parameters and approvals, commercial terms and packaging |
| Launch-readiness handover | Decision, reference and version | RFQ or production-release pack for the next stage | BOM, material and certificate scope, development parameters and approvals, commercial terms and packaging |
Project file to assemble
- Buyer focus: Brand owners, channel operators and sourcing teams.
- Page scope: first-assortment width, non-negotiable specifications, sampling budget and launch gates.
- Evidence to assemble: for first-assortment width, non-negotiable specifications, sampling budget and launch gates, approved brief and scope note; dated specification, BOM or official-source note; sample, test or registration record for the named reference; named approval, exception and change log; RFQ or production-release pack for the next stage.
- External dependencies: BOM, material and certificate scope, development parameters and approvals, commercial terms and packaging.
- Next step: send a dated brief covering first-assortment width, non-negotiable specifications, sampling budget and launch gates, the destination market and available documents for a feasibility review.
Buyer questions
What should be fixed before “Limit the first assortment”?
For first-assortment width, non-negotiable specifications, sampling budget and launch gates: Fix the channel, launch date, target customer, assortment, size curve, packaging route and evidence the channel expects. Leave expansion options visible but do not put every option into the first sample set.
How should “Prioritise non-negotiable specifications” be reviewed?
For first-assortment width, non-negotiable specifications, sampling budget and launch gates: Use the same approved sample, BOM and pack data for every option under comparison. Note which differences affect price, lead time, testing or reorder risk.
When is the project ready for a purchase order?
For first-assortment width, non-negotiable specifications, sampling budget and launch gates: When the approved sample, specification, artwork, test status, quantity, delivery terms and open-risk list are versioned and accepted by named owners.
