Broken texture of custom armor model

Hello everyone!

I wanted to "change" the player skin with my mod, so I made a model for a custom armor:

After I set it up in MCreator and opened the game it appeared like this:

The model and texture: https://drive.google.com/drive/folders/1NUGQrrb4DYYVRgK37c8loQCXPQ917UGf?usp=sharing

Any idea on how I could fix this?

Thanks in advance for anyone's response.
