A little bit of confusion (perhaps) has arisen. It may be simple misinterpretation, or knee jerk reaction to the word "Nude" but I'm going to define something called "Levels" here.
Levels are what models work to. Alongside price, it is one of the first things a photographer needs to discuss with a model. It covers what they are (And equally important ARE NOT) prepared to work to.
This is a list from a popular modelling site. It's pretty much in alphabetical order rather than by style. I've notated the levels with what they are.
Wedding Why a model would only do "Weddings" is a mystery, but it is a level.
