Your child will be the cutest kitty on the block with this adorable costume from Pottery Barn. The mask is very comfortable and has a velcro closure at the chin. The back of the costume closes with velcro as well. The body of the costume has some thickness to it to help keep your little one warm. The tail on the back of the costume can be left to hang free OR it has a velcro tab to stick the tail to the back of the costume (pictured).
