I want to represent fantasy!

Hello! This is my first post on the subreddit and I need help.

In two days is my school graduation and what supported me the most in this period of growth from 13 to 18 years old was the creation of fantasy worlds, for the same reason on the day of my bachelor's degree I want to have at least some element that be characteristic of classic fantasy in general, something that says "this girl is obsessed with magic, dragons and knights." This genre of literature gave me the happiness I needed to move forward and now I want to have a small detail that remains in the photos of the event.

I'll wear black loafers, loose black fabric pants, and a navy blue blouse with the sleeves rolled up... If you come up with something, I'd be happy to read your suggestions.
