Hey, who shrunk Batman? When your youngster hits the streets in our Batman Kids Muscle Costume T-Shirt, that's the question that'll be on everyone's lips! Or maybe somebody's lips! Or maybe that one guy, who always wanders the streets of your town, muttering gibberish to himself? This 100% cotton t-shirt is sure to bring out the superhero in your kids' imagination! In addition to the super-cool Batman costume that it replicates, it even features the six-pack abs Bruce worked so hard to develop! And a completely non-functional utility belt, to keep all those imaginary Batarangs and Fruit Roll-Ups in! Not to say he couldn't keep a very real Fruit Roll-Up in his back pocket while he's wearing this shirt!
