A Key Insight

by Abby Keul

In 2023, a Serbian-Hungarian research confirmed publicly what we knew: design parameters are flexible. This key insight — that a garment's width and length can move within a tolerance range without changing how it looks — has been sitting underused in the pattern room for decades.

The paper, Flexible Design of Garment Styles to Support the Minimal Waste Concept in the Fashion Industry (Vilumsone-Nemes, Pešić & Csanák, 2023), tested four garment styles in real production conditions: a bell skirt, a dress, a blouse, and a blazer. For each, they made small reductions to width and length — amounts that left the design visually unchanged — then measured the impact on markers.

The results were consistent across all styles. A 2cm reduction in skirt length reduced fabric consumption by 3–5%. An 8cm reduction in the hem width of a dress reduced it by a further 2.5–5%. When both parameters were reduced together, fabric consumption fell by over 7% per marker. Across a production run, that adds up fast.

What makes this research significant isn't the percentages — it's the framing. The authors argue that garment design has always been treated as fixed, when in reality it never needed to be. Every style has a tolerance interval: a range of values for each construction parameter within which the design concept holds. A skirt can be 7cm wide at the hem or 11cm wide and still be recognisably the same skirt. That gap is where efficiency lives.

The paper goes further and calls for exactly the tool that doesn't yet exist: software that lets designers define those tolerance intervals, then automatically generates the full set of pattern variants and screens them against real manufacturing orders to find the most efficient combination. The authors name CLO 3D explicitly as the 3D visualisation platform where this process should begin.

That's what FashCompactor is building.

The bridge between what a designer intends and what a factory cuts has always been wider than the industry acknowledges. We're building the infrastructure to work in that gap — parametric pattern blocks with defined tolerance intervals, tested against real markers, with efficiency and carbon impact measured at the design stage rather than discovered on the cutting room floor. The research exists. Methodologies are documented. The tools are finally in development.
