How is body length typically measured in garment design?

In garment design, measuring body length from the back collar to the hem is a standardized practice. This measurement provides a consistent point of reference for designers, as it accounts for the natural fall of the garment from the neckline, which is often the highest point in a garment, down to the hem. By starting from the back collar, designers ensure that the measurement reflects how the garment will hang when worn, making it essential for achieving the correct fit and proportions.

This method is particularly important in the context of structured garments, such as blouses, coats, and dresses, where the silhouette and garment drape can significantly affect the overall appearance. While other measurement methods may be relevant in different contexts, such as measuring from the shoulder or waist, the chosen option accurately reflects industry standards for body length measurements in most apparel.
