12-18M Disney•Pixar Monsters University infant costume NWT

Adorable Monsters Inc. Sulley costume comes with soft booties, a detachable tail with velcro, and a headpiece complete with soft horns and fuzzy hair on top. The costume says 12-18 months, but in my opinion, it runs a little small. My average-sized son tried it on at 8 months old, and it was a perfect fit!
