This case study details how Sansansun’s expert pattern-making and systematic feedback process solved a critical sizing inconsistency issue for a children’s loungewear brand. By rebuilding the patterns from scratch and implementing a rigorous feedback loop, we controlled size variation to within ±0.5 cm, restoring the client’s confidence and solving a problem that had plagued their business.
Client Profile: A Brand Troubled by Fit Issues
Our client is a brand specializing in children’s loungewear. Their core challenge stemmed from previous experiences with other suppliers where inconsistent sizing had become a persistent issue, directly impacting their brand reputation and operational efficiency.

The Challenge: When Inconsistent Sizing Erodes Customer Trust
The brand was facing critical issues that were damaging their customer relationships and bottom line:
- The same size would vary significantly from one production batch to the next.
- Parents frequently complained that the garments were too tight, too long, or too short for their children.
- This resulted in poor customer try-on experiences, high return and exchange rates, and a decline in overall brand satisfaction.
- The client had lost confidence in their ability to scale up production reliably.
The Solution: A Systematic Approach to Perfecting Fit
We addressed the problem not with a quick fix, but with a systematic, collaborative process from the ground up:
- Step 1: In-depth Consultation: We began by holding in-depth discussions with the client to clearly define the target age groups, wear scenarios, and specific fit requirements.
- Step 2: Rebuilding Patterns: Our experienced children’s wear pattern-making team created brand new, child-specific pattern blocks, tailored for comfort and accurate proportions, rather than simply grading adult patterns.
- Step 3: Systematic Feedback Cycle: We established a formal feedback loop. For each sample, the client provided detailed try-on feedback (e.g., “sleeves are 1cm too short”), which was systematically recorded.
- Step 4: Precision Adjustments: Our pattern makers treated each piece of feedback as a critical data point, making precise adjustments. We ensured the final pre-production sample was a 1:1 reflection of all revisions before locking it for bulk production.

The Outcome: Precision, Confidence, and a Reliable Partnership
The results of our systematic approach were clear and decisive. The client’s sizing nightmare was transformed into a reliable and predictable process.
- Precision Manufacturing: The final bulk order was delivered with every single piece precisely matching the approved sample.
- Tight Tolerance: Size variation across all sizes (e.g., 2T, 3T, 4T) was successfully controlled to within ±0.5 cm.
- Restored Client Confidence: The client expressed immense relief and satisfaction, stating, “This is the first time I feel completely safe handing over children’s sizing to a factory”.
This case highlights our core strength: we don’t just grade patterns — we co-develop the perfect fit through a proven cycle of trial, feedback, and refinement.
