Just the right moves

Ron's sister was in the fashion industry.  She knew that Ron loved to dress so much that he would be her model once in a while when she was creating a dress. She was also a witch and could make Ron into any woman she or he desired. She needed him to help model bikinis,as one of the booked models had come down sick.  She was concerned that he didn't have the right moves for the runway, where she really needed him.

 

He convinced her that he did.
