Turn movie night, a cozy costume party or a lazy winter weekend into a laugh with this red big-mouth monster onesie. It is a one-piece hooded jumpsuit in a loose, oversized cut, with a cartoon monster face on the hood: big googly eyes, a wide, padded light-blue mouth and a tuft of blue fluffy pile on top. A small monster face peeks out of the front pocket to match. Pull the hood up and the monster's mouth sits over your head for an instantly silly costume; push it back and it is simply a warm fleece lounge suit.
