The 95%cotton/5% spandex Batgirl LS V-Neck Caped Costume T-Shirt features athletic stripes on the sleeves, the Batsymbol and a cape for crime fighting. You don't actually have to fight crime even though you're wearing a cape. Unless you want to join the ranks of the Dark Knight. Then hey, this Batgirl LS V-Neck Caped Costume T-Shirt is your first step into getting that perfect outfit together. Or you can be like me and just jump around, karate chop, and kick while yelling BAM, POW, THWACK at your co-workers. Yeah.
