A wild (or mild) fashion shoot will help your designs rival what has been done or blend with what already has been done.
A lot of my fashion work is "from scratch" and not a reference point can be found from client to client. This is probably the area where I am the most free in my lighting and posing choices. Fashion needs to be bold. Whether it's color, the designs themselves or the unpredictable nature of being on location and working with what you've got.
