When we think of bokeh, we normally of out-of-focus areas behind the subject. But the nature of depth of field means there are out-of-focus areas in front of the subject as well, and taking advantage of these can create some unique portraiture.
Making these interesting images is surprisingly easy and doesn't take much extra equipment. Much like relatively distant light sources behind a subject can create beautiful balls of diffuse bokeh, the same can happen for light sources in front of the subject. In this case, however, it creates a more ethereal effect, with the subject seemingly inside a world of light as opposed to being in front of it. Just be careful not to overdo it, as you don't want your subject competing with the bokeh. Paying attention to how you frame your model with the lights and how many are in the image should take of that.
