It took him a few tries to get the wand movement down, but as soon as he felt ready, Theo nodded to himself and positioned him and his wand distance properly. The first few go's hadn't gone to plan, but he just kept thinking back to the first lesson, and it helped a little...

"Summus Vestis!" Yay, something had happened! The rubbish bag transformed into... wait.... what? A T-SHIRT? A t-shirt on the legs of the mannequin? Theo smacked himself across the head, cos he realized that he'd used the wrong spell. It was bound to happen since he was thinking back too much.

B-b-b-b-but he just did not feel comfortable with the reversing spell, so he was just gonna continue from here.

"Summitto Vestis!" He said, using the correct wand movement, and the T-shirt transfigured into a very small pair of trousers. They looked very tight on the poor mannequin. "Sorry, dude." But that was good enough for Theodore! YEp!
