What is the role of dressers during a production?

The role of dressers during a production primarily involves helping performers into their costumes. Dressers play a crucial part in ensuring that actors are dressed appropriately and on time for their performances, which is vital for maintaining the overall flow and professionalism of the production. They provide support in putting on complex costumes, making adjustments as needed, and ensuring that any required accessories are properly positioned. This backstage function is essential for the performers to focus on their roles, as they don't have to worry about their costumes when they have dedicated personnel attending to that aspect.

In contrast, the other options involve different responsibilities that are not within the typical scope of a dresser's role. Assisting actors with props pertains to prop management, which is a separate function. Managing sound effects is the responsibility of the sound department, and controlling stage lighting falls under the duties of the lighting crew. Each of these roles is critical to a production but serves distinct purposes apart from that of the dressers.
