Sample costs range from $30–$250 per sample depending on garment complexity. A properly managed sample process is the single biggest driver of on-time, on-spec production. For a comprehensive overview, see our [buying house in Bangladesh — complete guide](https://taeen.com.bd/) guide. International brands frequently underestimate the sample development phase. They allocate two weeks in their calendar, get frustrated when it takes eight, and end up either rushing into bulk production with an unapproved sample (expensive) or missing their seasonal window. This guide gives you the real timelines, the real costs, and the process that prevents both outcomes. For a full breakdown of the overall production timeline from order placement to shipment, see our guide on [garment production lead times in Bangladesh](https://taeen.com.bd/blog/lead-time-garment-production-bangladesh). For the tech pack documentation that drives the sample process, see our [tech pack guide for Bangladesh manufacturing](https://taeen.com.bd/blog/tech-pack-bangladesh-apparel-manufacturing-guide). ## The Three-Stage Sample Development Process ### Stage 1: Proto Sample (Development Sample) The proto sample is the first physical interpretation of your design. It is produced from the tech pack alone — without confirmed fabric, colour, or trims. Its purpose is to validate construction and fit before committing to production fabrics. **Timeline:** 3–4 weeks from confirmed tech pack submission to sample dispatch. **Typical cost:** $40–$120 per piece depending on garment complexity. A basic jersey T-shirt proto costs $40–$60; a structured woven jacket with multiple panels costs $100–$180. **Fabric:** Substitutes are acceptable at proto stage. The factory will use the closest available fabric from their stock rather than ordering production fabric. Communicate this clearly to your design team. **Key actions for the buyer:** - Provide a complete tech pack before placing the proto sample request — incomplete tech packs are the #1 cause of proto sample delays. - Evaluate construction method, seam placement, pocket depth, closure function — not colour or fabric. - Provide clear written comments on every point that needs changing. Verbal feedback via WhatsApp causes miscommunication. ### Stage 2: Fit Sample (Sealing Sample / Confirmation Sample) The fit sample incorporates proto sample comments and is produced in the actual production fabric and confirmed colour. This is the sample your design team fits on a body form or live fit model to confirm measurements, proportions, and wearability. **Timeline:** 2–3 weeks from proto approval and comments. Add 1–2 weeks if production fabric needs to be ordered from a mill rather than taken from stock. **Typical cost:** $50–$180 per piece (production fabric is used, so fabric cost is included). **Key actions for the buyer:** - Conduct a proper fit session with the sample on a calibrated dress form or fit model before providing comments. - Confirm all trims — buttons, zippers, labels, hangtags, care labels — at fit sample stage. Late trim changes are a major cause of PPS delays. - Aim for one fit sample round wherever possible. Multiple rounds add 2–3 weeks each. ### Stage 3: Pre-Production Sample (PPS / Top of Production) The PPS is produced from bulk production fabric, bulk trims, and the confirmed construction. It is the final approval before bulk cutting begins. Once the PPS is approved, the factory proceeds with bulk production. **Timeline:** 1–2 weeks from fit sample approval. **Typical cost:** $30–$100 per piece (often charged at or near cost since it uses bulk materials). **Critical rule:** Never approve bulk production without an approved PPS. Bulk production initiated on a fit sample approval — without a PPS — is one of the most common causes of bulk quality failures in Bangladesh. The PPS approval also triggers the [buying house production monitoring process](https://taeen.com.bd/blog/buying-house-process-guide), including cutting ticket approval, inline QC scheduling, and shipment planning. ## Sample Development Timeline: Full Picture | Stage | Duration | Cost per Sample | Fabric Used | | --- | --- | --- | --- | | Proto sample | 3–4 weeks | $40–$120 | Substitute stock fabric | | Fit sample | 2–3 weeks | $50–$180 | Production fabric | | Pre-production sample (PPS) | 1–2 weeks | $30–$100 | Bulk production fabric & trims | | **Total (typical)** | **8–12 weeks** | **$120–$400** | — | Add 2–4 weeks for each additional revision round required at any stage. Complex garments (outerwear, structured jackets) with multiple revision rounds can extend total development to 16–20 weeks. ## What Causes Sample Development Delays? In TAEEN's experience managing sample development for 50+ brands annually, the most common delay causes are: - **Incomplete tech packs:** Missing measurements, unclear construction details, or unspecified trims force the factory to guess — and guess wrong. - **Slow buyer feedback:** Factories wait for buyer comments before proceeding. A buyer who takes 2 weeks to review a sample adds 2 weeks to the timeline. - **Fabric sourcing delays:** Production fabric ordered from mills takes 3–5 weeks to arrive. If the buyer changes fabric specification after proto approval, the fit sample timeline resets. - **Multiple revision rounds:** Every additional proto or fit sample round adds 2–3 weeks. Investment in a detailed tech pack upfront reduces rounds significantly. - **Trim unavailability:** Branded buttons, custom zippers, or woven labels with lead times of 4–6 weeks can delay fit and PPS samples if not ordered early. ## How a Buying House Accelerates Sample Development A professional buying house like TAEEN shortens the sample development cycle in several concrete ways: - **Tech pack review before factory submission:** We review every tech pack for completeness before submitting to the factory, catching ambiguities that would otherwise cause revision rounds. - **Factory pre-qualification:** We match each style to a factory with proven capability in that product — reducing the likelihood of construction errors at proto stage. - **Proactive timeline management:** We track every sample against a shared timeline and chase factories before deadlines are missed, not after. - **Trim sourcing:** We source custom trims in parallel with sample development, so they arrive in time for the fit sample stage. ## Sample Costs: Budgeting Realistically For a 10-style collection with one proto, one fit, and one PPS per style: - Proto samples (10 styles × $80 average): $800 - Fit samples (10 styles × $120 average): $1,200 - Pre-production samples (10 styles × $70 average): $700 - International courier (DHL/FedEx, 3 shipments): $600–$900 - **Total sample budget: $3,300–$3,600** Budget an additional 30–40% for revision samples if your collection is new to Bangladesh production or involves technically complex construction. ## Conclusion Sample development is the foundation of every successful Bangladesh production program. Invest in a complete tech pack, plan realistically for 8–12 weeks, respond to factory samples promptly, and never cut bulk without an approved PPS. TAEEN manages the full sample development cycle — from tech pack review to PPS approval — for brands across all product categories.
