Which process involves taking measurements and making sketches for costume creation?

The process of taking measurements and making sketches for costume creation is best categorized under costume designing. This process is crucial because it lays the foundation for how a costume will look and fit on a performer. Costume designers must consider the character's personality, the setting of the play, and the overall visual aesthetic of the production while creating detailed sketches and obtaining accurate measurements.

By focusing on these elements, costume designers ensure that the costumes are not only visually appealing but also functional for the actors’ movements and interactions on stage. The work they do establishes a guideline for the construction team, allowing them to bring the design into reality. This highlights the significance of the costume designing phase as a necessary step before any actual construction techniques are employed.
