Than I would suggest bring those other issues up with communication. if there was something that triggered the change in her, you should let her know you would like to understand.

Everyone should have the freedom to express themselves through their appearance, you can't ask for that.

However, you can ask for her to put more work into your relationship with smaller gestures of love. Or look up love languages and tell her that you want her to express her love through that. And of course do the same.

Just don't expect someone to change or wear certain things just to please you.

do what you want then bro.
