3D fitting is an innovative product combining digital simulation technology with virtual reality. With the help of computer information processing technology and graphics principles, the user's body information is processed to form a relatively similar three-dimensional human model, so that the virtual model can be worn on the corresponding clothing products, and the user can observe through the system to achieve better fitting effect.

The following is the correct way to use 3D fitting:

1. Take photos or videos: Take your own photos or videos with your smartphone or professional camera. Make sure that the background in the photo or video is solid color, so as to better display the clothing.

2. Upload photos or videos: upload photos or videos to the 3D fitting application.

3. Choose clothes: Select clothes to try on in the application.

4. Size adjustment: Adjust the size of clothes as needed.

5. Preview: Preview your appearance and see if the clothes suit you.
