Super cute and comfy Pikachu onesie! This is an adult's size large, and easily fits me (5'10"). The body is roomy enough to fit a wide range of body types, and even my brother (6'5") was able to wear this although it did make the legs a bit shorter 😂 There are pockets, and a butt zipper! The front buttons and the adorable hood has a face and ears on it. This is also quite warm, if you're planning to wear outside on Halloween! 🎃
