How do tailors measure length of gowns?

Tailors measure the length of gowns by starting from a specific point, usually the shoulder or the neckline, and extending the measuring tape down to the desired hemline. They may take into account the wearer's height and the type of shoes they plan to wear. Additionally, for more intricate designs, they might also consider factors like the gown's silhouette and any intended train length. Accurate measurements ensure the gown fits perfectly and achieves the desired style.
