Never force yourself to stick to one aesthetic (unless you perfectly fit into that box haha). My main advice is to explore aesthetics and try new things! I started by looking through this wiki's entire list of aesthetics and noting down every single one that I liked. Now I have a list of at least 20 aesthetic that I could use to describe myself. Your personal aesthetic is always going to be unique/ a mixture of things, because no two people are entirely the same.

Some fun ways to experiment with aesthetics is by making pinterest boards. You can search up images for certain aesthetics and certain vibes/ colors that you're interested in, and I found that this really helps me. From there you can try personalizing things such as our phone wallpaper or social media accounts.

Overall, my main advice is to just have fun! Your aesthetic is uniquely yours, and it's most likely that you won't fit into a box. Also, people seem to ask anybody with a darker aesthetic/ style if they're an e-person, so don't let that get to you :)
