This costume consists of a once piece outfit with a red lightning McQueen muscle shirt top attached to the black legging bottoms.  It also includes a soft foam hat.  The hat is not a typical baseball hat, much softer.  However, this is a great costume on the whole.  Also, all you need to add for a complete costume is shoes.  I hate getting a costume that needs some kind of additional garment to complete it, and that is not the case with this costume.  My 2 1/2 year old son was happy to put this on and its comical to see him with muscles.
