Himself

Fortunately for the handful of people hurrying by none of them catches the budding witch's attention. Instead, he decides to test the powers on himself.

He briefly considers trying to turn back into a man. After all he'd switched the loudmouthed builder's gender easily enough. But ultimately decides against risking such a big change. Instead he elects to try and do something about the ridiculous outfit he's squeezed into.

If his new found power was responsible for dolling him up like an add for slutty Halloween costumes then surely he could use it to conjure up something a bit more practical?
