Because no one has ever made a Powergirl shirt and Karen Starr in the new DC Universe is a costume without Wally Wood’s design here is something you can print off and make your own as an iron on.
Rememeber, iron to a white shirt.
But if you use this, make sure to send a photo. So I can post it.
And my apologies to Threadless for stealing this image to post what the Powergirl thing should look like on another person.
Link to the iron on.
