Your staples?

Over the last few years I have found much joy in figuring out what my staples are. I have figured out my lipstick color and my perfume. Are there other aspects of personal style that fit that category, I know my style pretty well but are there any other classic aspects that I might be missing? I have my signature lip color. I have my signature scent. I have my everyday shoe. What are other things that we make signature? Any tips on what to look at next?
