Children enjoy structure...you should probably try to get them enrolled in the Imperial Daycare Center. Not only will they learn important life lessons like hating rebel scum, practical applications of the Dark Side, and sounding like James Earl Jones but they will also gain access to the 90% cotton 10% polyester Star Wars Kids Vader Obey T-Shirt! This soft heather grey t-shirt has a red inner ring around the sleeves and collar while featuring a rather imposing Darth Vader asking to simply be obeyed. Like I said, kids like structure...and the Star Wars Kids Vader Obey T-Shirt!
