I am going to make the waistcoat to fit a man, male measurements, and then put the waistcoat on a female model, but style the female model, to look like a boy.

This is an image of Queen Of Pop, Madonna. This image inspired me, as the boyish stance creates a different look to the photo. Also, the fag in her hand shows an un lady-like look.
