Fionna's bunny-eared hat is a defining aspect of her character. You can find replica hats online or create one yourself using white fabric or fleece. The hat should fit snugly over your head with two prominent, long bunny ears standing upright.

Fionna wears simple black Mary Jane shoes, which you can pair with dark knee-high socks. For accessories, a green backpack is essential to mimic her adventurer's gear. If you're including a sword as a prop, choose a safe, toy version or make one from foam or cardboard.

To fully embody Fionna's character, focus on her energetic and bold personality. Fionna is adventurous and often jumps into action, so portraying a sense of confidence and readiness for adventure will enhance the costume. Also, if you can, replicate her blonde hair, either with your own hair or a blonde wig styled in long, flowing locks.

Including some of Fionna's quotes can make your costume portrayal more authentic. Memorable lines include: "I don't need to feel like I'm waiting to be noticed. I know who I am, and I'll know what I want if and when it ever comes along.," "Adventure Time!," "Sword-fighting is like making a promise. It's about letting your opponent know you're about to hurt them.," "This day has been lousy, but I'm not going to let that ruin how awesome the night can be!" and "Come on, let's go explore!." These quotes capture Fionna's self-assuredness, her love for adventure, and her optimistic outlook.
