ABOUT FIONNA:

Fionna, the fearless heroine of the Adventure Time spin-off series, is a force to be reckoned with. As the genderbent counterpart to Finn the Human, Fionna shares his adventurous spirit and thirst for excitement, but with a unique twist. Portrayed as a young adult struggling to find her place in a mundane world, Fionna’s journey is one of self-discovery as she navigates the magical realm of Ooo alongside her loyal companion Cake the Cat.

How To Dress Like Fionna

1. T-SHIRT – Our Fionna costume begins with a light blue tee with 3/4-length sleeves.

2. SKIRT – Next, you will need to add a mini pencil skirt in dark blue.

3. SOCKS – These white tube socks with blue stripes are very similar to the ones worn by Fionna.

4. BACKPACK – We love this Adventure Time-inspired backpack, and not just for this costume either! If you want to make a Finn outfit, then this is still the backpack to go for.

5. HAT – This Fionna hat, complete with bunny ears and blonde fringe is absolutely perfect!

6. SHOES – Finish with a pair of black flats and your Fionna outfit is officially ready for Halloween or any cosplay event!

Fionna of the Adventure Time spinoff ‘Fionna and Cake’ had some pretty big boots to fill taking the place of Finn but we think she did it admirably!
