T-Rex Children's Costume can be played two ways. The scaly green jumpsuit was made to instill fear with teeth that look razor sharp and spikes that run from head to tail, but there is no denying that the funny little arms are cute. Your kid can go full on face paint and snarl his way from house to house, or put on a smile and wave his arms to make other trick-or-treaters laugh. Either way, this T-Rex Children's Costume is sure to be a prehistoric hit.
