How we do it – the BlitzResults Lab

In the BlitzResults lab, our approach is straightforward and focused on delivering results. The space is set up for efficiency, with workstations equipped with the necessary tools for precise garment measurement: measuring tapes, digital calipers, and detailed spreadsheets for data entry.

The process begins with a pair of jeans, for example, from Levi’s. Each item is prepared for measurement by laying it out flat to ensure accuracy. Key dimensions such as waist, inseam, hip, and thigh are measured meticulously to eliminate errors. These measurements are then recorded into a database alongside the official size charts provided by Levi’s.

The critical stage involves analyzing these measurements against Levi’s published size charts. Our team uses analytical software to identify any discrepancies, focusing on areas where the actual measurements diverge from those listed by Levi’s. This comparison is grounded in the practical goal of identifying and correcting inaccuracies to improve sizing reliability.

We also align our findings with the standards set by the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO). This ensures that our size charts not only reflect real-world measurements but also adhere to internationally recognized sizing standards, providing a dual layer of credibility to our work.

Based on this comprehensive analysis, we draft revised size charts that reflect our empirical findings and standardization alignment. These drafts undergo a validation process, including fit testing on mannequins or live models to confirm the practical accuracy of the proposed sizes.

Final adjustments are made based on the outcomes of these tests, ensuring that the size charts we produce are both accurate and applicable to real-world use. Once finalized, these charts are made available to our clients, but our commitment to accuracy doesn’t stop there. We maintain an open feedback loop, allowing for continuous improvement based on real-world application and client feedback.
