1. Make a dressing plan: arrange the performance time and program sequence of each child in advance, and determine the appearance time and the time period when you need to change clothes.

2. Prepare necessary clothes and accessories: prepare enough clothes, shoes and accessories. And prepare corresponding clothes for each child. If children bring their own clothes, they need to check in advance and inform parents to mark them clearly to avoid confusion.

3. Layout of dressing places: You can set up a dressing area in the dressing room or behind the stage, equipped with large mirrors, hangers and other necessary tools to facilitate children to change clothes quickly.

4. Organize the try-on session: Children can be organized to try on before the competition, so that they can know which clothes need to be worn together to avoid wasting time when changing clothes.

5. Arrange instructors: In order to complete the dressing process in an orderly manner, some parents, volunteers or teachers can be arranged to help children change clothes and give necessary guidance and help.

6. Encourage children to do it themselves: If children are older, they can be encouraged to try to change clothes themselves to improve their independence and self-care ability. However, for young children, adult guidance and help are needed.

7. Use portable lockers: If space permits, lockers can be set up to store children's clothes, which is convenient and quick to avoid confusion. You can use ready-made portable lockers or build your own on the website.
