In the world of high-street manufacturing, speed is the primary metric.
To achieve volume, these brands typically use 8-10 Stitches Per Inch (SPI).
The Speed vs. Longevity Divide
A 10 SPI seam is fast to produce and uses less thread, but it creates a fragile bond. Within months, the stress of the wash cycle causes these loose stitches to pull, leading to the "Six-Month Collapse" where the shirt loses its structural integrity and the collar sags.
Made in Italy: 15 SPI
In our Italian workrooms, the standard is 15 Stitches Per Inch.
-
The Engineering: 15 SPI takes significantly longer to sew and requires a higher level of precision from the tailor.
-
The Result: The result is a seam that is effectively fused. It is the technical foundation of our 100-Wash Promise, ensuring shirts such as our Barga and Lucca maintain their original shape long after high-street alternatives have failed.
-
The Collar: This density provides the internal architecture required for a Cutaway Collar to remain upright and sharp from 9 a.m. to 6 p.m.
The Technical Advantage
By prioritizing the 15 SPI standard, Vestiti maintains a 0% Return Rate on quality and fit. It is the difference between a garment made for a season and one engineered for years of performance.
