I usually wear dark heels with dark stockings, however I have worn gold shoes with black looked good with a black dress.
If I'm using a professional photographer I follow their styling guidance either from themselves, looking at their gallery or from their make-up artist if using one.
When taking my own photos I'm more experimental, but do take ideas and inspiration from posts by other escorts, some client suggestions, following a range of models and photographers usually pin-up or fetish style.
I know quite a few client suggestions don't work, but have been reluctantly surprised by a few - this then inspired videos and photos for private gallery sales.
