From product idea to a reviewed sample
Sampling &
Prototyping.
Make the details count.
Develop your underwear or knitwear sample around the decisions that matter: fabric, fit, construction and brand details.
Scope, fees, timing and revisions agreed for your project.
What a sample helps you review
01 / Start where you are
Bring your references.
Define the next step.
Your brief does not have to be complete to begin a conversation. Share what is available and identify what still needs a decision.
A tech pack
Share drawings, measurements, material targets, construction notes and artwork.
A reference garment
Explain what should stay, what should change and how the new product should fit.
A sketch or concept
Describe the category, target customer, intended fit and the details you want to explore.
BSTAR’s own factory focuses on sewing, packing and shipment. Fabrics and trims are sourced through long-term suppliers. Any pattern development, grading or technical-document work needed for your sample is scoped during review.
02 / A development route to agree
Clear checkpoints.
Room to refine.
Use these stages to plan the work and approvals. The sample types, sequence and number of rounds are agreed around your product.
- 01
Review the brief
Clarify the product, intended fit, references, target quantity and the question the sample should answer.
Checkpoint / Sample purpose - 02
Check materials & details
Review fabrics, trims, colors and branding. Identify any proposed substitute and the limits of using it.
Checkpoint / Material plan - 03
Agree the sample plan
Define sizes, sample quantities, development tasks, fees, timing and the review or shipping arrangements.
Checkpoint / Agreed scope - 04
Make & review the sample
Use the agreed sample to assess measurements, fit, materials, construction and details against the brief.
Checkpoint / Sample feedback - 05
Resolve the changes
Consolidate comments, clarify revisions and decide whether another sample or a focused check is needed.
Checkpoint / Revision decision - 06
Record the approved reference
Identify the approved sample and specifications, then confirm any open items before bulk production.
Checkpoint / Approval record
A revision can return the project to an earlier checkpoint. Confirm the effect on materials, cost and timing before the next round.
03 / Review with a purpose
Look beyond
the first impression.
A useful review connects what you see and feel to the agreed specifications. Record the sample version, comments and the decision for each item.
Review criteria are adapted for women’s underwear, T-shirts, tanks, thermal sleepwear and other knitted garments.
Shape, size & movement
Review the intended fit and agreed measurement points. Note where the sample feels tight, loose, short or restrictive.
Material in context
Check hand feel, weight and stretch against the sample purpose. Record whether the material is final or a substitute.
Seams & garment details
Review stitching, joins, openings and relevant details such as a pouch, gusset, waistband or neckline.
Placement & finishing
Check the size and position of artwork, labels and trims. Confirm which packaging details are included in this sample round.
04 / Set expectations before starting
Know what the
sample plan includes.
Confirm these three areas together so the sample, review and delivery arrangements match the work being requested.
Scope & cost
- Development tasks and sample quantities
- Fabrics, trims, branding and packaging
- Review records or testing requested
- Shipment costs and any agreed fee credit
Timing & delivery
- Specification and artwork readiness
- Material availability and sourcing
- Sample making and review time
- Shipping destination and transit planning
Revisions & approval
- Comments included in each review round
- Changes to the original specification
- Need for another sample or new materials
- Approval method and final reference version
Sample fees, schedules and revision arrangements are confirmed after reviewing your project.
Review my sample requirements05 / Prepare the production handover
An approved sample.
A defined next step.
Sample approval should identify exactly what has been accepted. Confirm remaining materials, specifications and order terms before releasing bulk production.
Sampling and bulk MOQ are separate.
A sample order does not establish the production minimum. Review MOQ against the final style, fabric, color allocation and branding.
Explore MOQ & order planningConfirm for your project
- Approved sample & specification version
Identify the physical or agreed reference and record outstanding differences.
- Measurements & construction
Confirm the agreed measurement chart, size range and garment details.
- Materials, artwork & packaging
Resolve substitutions, colors, trims, label content and packing requirements.
- Order & inspection requirements
Agree quantities, applicable MOQ, pricing, timing and quality checkpoints.
06 / Practical answers
Before your
first sample.
A clearer starting point helps both teams plan development and review.
Ask about your projectCan I start without a complete tech pack?
Yes—start by sharing your reference images, sketches or sample description, together with the product category and intended fit. We can review what information is missing before agreeing the next step. Pattern development, grading or technical-document preparation, if needed, must be discussed and included in the agreed scope.
How long does a sample take?
Timing depends on the completeness of your brief, material and trim availability, construction, sample quantities and revision needs. Sample making, your review time and shipping should be planned separately. Share your target date so a suitable schedule can be discussed after reviewing the specification.
How much does sampling cost?
The sample quote depends on the work required, materials, sample quantities, branding, revisions and shipment arrangements. Confirm what is included before starting. Any credit of sample fees against a bulk order must be expressly agreed for that project.
Can I send a reference sample or my own fabric?
Tell us what you would like to send before arranging a shipment. A reference garment can help explain fit or construction; supplied fabric needs a suitability and quantity review. If an alternative material is proposed, agree whether it is suitable for the purpose of that sample.
What if the first sample needs changes?
Combine your comments into one dated feedback list with photos, measurements and a clear reference to the sample version. The next step is to review which changes are needed, whether another sample is required, and how the changes affect the agreed scope, fees and timing. Revision rounds are confirmed per project.
Will a prototype use the final production materials?
Confirm this in the sample plan. An early prototype may use an agreed substitute to review fit or construction. That substitute does not establish the final color, hand feel or performance of the production material. Record any differences and decide what needs further approval.
Does sample approval mean bulk production can start?
Sample approval is one part of the handover. Final specifications, material and trim choices, size and color quantities, packaging, applicable MOQ, price and production timing still need to be agreed. Record which sample and documents are the approved reference.
Can you review samples for products beyond men’s underwear?
Men’s underwear is our core focus. We also work with women’s underwear, T-shirts, tank tops, thermal sleepwear and other knitted apparel. Share the category and construction requirements so the scope and feasibility can be reviewed for your product.
