Mirror scene reflection

I have made a mirror reflection scene, but I need to duplicate the character. The problem is, is that I made the readers able to customize the MC. Meaning It’ll look like there are different characters, one looking at the mirror and the mirror reflection would look different if they were to customize the MC. How do I fix this?

Right before the mirror scene use this code:


It will make the duplicate identical to the MC

Ah thank you so much <3
