If you think you love Hello Kitty, think again. Unless you've attend Hello Kitty's Supercute Friendship Festival, you won't know exactly the amount of love there is for her. Fans who went to the festival are incredible at putting their own spins on dressing like Hello Kitty.

At the festival in Oakland, CA, people showed up in their best outfits honoring the beloved cartoon — and some were even influenced by the Bay Area. These are definitely true die-hard fans who already know everything [1] about her, including that she's no longer looking for love [2].

Check out our favorite costumes ahead and maybe you'll get inspiration on how to take your love for Hello Kitty to the next fandom level. Halloween [3] ideas, anyone?
