How do you bridge the gap between the basics and adding your personal style?

Hello, Recently joined and looking to build out my wardrobe basics on a budget while at the same time trying to build out my own sense of style. Any advice to a novice how to create your feeling of "self" through clothing? This question comes from the fact that I personally have a large disconnect of the fit pics and brands I enjoy to view online versus what I actual wear or present myself. (see attached photo) For instance, I wear very basic clothes/old tshirts left over from college/cheap shoes. But I like to follow very high-end designer clothes, which include very unusual articles and sometimes outrageous outfits. Do you all have any suggestions for me on how to "meet in the middle" for expectations, style, or design? I'm thinking starting with a solid foundation and experimenting from there, but I would like to hear other thoughts. Thanks in advance 🙂
