Does someone know how to make clothes shine at night?

So i make a spritepack but i'm not into coding very much, but i want to make like some elements on her clothes shine at night like this with her top, but i make a full body spritepack and not only top so i don't think code in this json can help with what i'd like to do, also i would love if someone could give me some sprite pack like this so i can steal- i mean borrow code in json file
