Context: academic writing. If I want to say women love luxury fashion very much. They spend a lot on it. They are very into it. So, if one destroys a woman's luxury clothes, she will definitely go crazy. I wonder if there is a metaphor or word or any phrase that can represent the importance of luxury clothes to women. Can I say something like: luxury clothes are a woman's lifeblood? I want it to be a formal one for the sake of academic writing.
