If you are stuck on your aesthetic try looking into these different aesthetic branches: The academia aesthetics, nature aesthetics (cottagegore, goblincore etc.), more femenine aesthetics (baddie, boujee, girly etc.), dark aesthetics (grunge, punk, crypitdcore etc.), more soft aesthetics (kawaii, angelic soft etc.), vintage aesthetics and so on. Consider thinking what type of colours you prefer, what decade and what you prefer doing in your pasttime. Aesthetics aren't all about what you wear, but about what you enjoy doing. Try also taking some online tests which will help you.
