I've done a few shoots with Dominatrixes. I can't say that I completely understand or appreciate the fetish, but I do like the imagery and the high contrast of the clothing and accessories. I like the short depth of field of this shot.
When posing a model, rather than just saying "hold up your hands and look to the left" it can work better to give a model a starting point and follow her lead. This model was a fan of 1930s icon Josephine Baker, so I said, be Josephine Baker. And she did.
