Mabel Pines has got life figured out. When she’s not busy bedazzling her face, she’s honing her grappling hook skills or pigging out on some Smile Dip. And fashion sense? Forget about it!

Any girl can give it a try with this Gravity Falls costume, but you need to have a zany sense of humor and an unquenchable thirst for adventure in order to wear it!
