I disagree. If a model is comfortable posing nude for photographers, why wouldn't he/she be comfortable doing the same for artists with pencil or paintbrush? Life modelling also isn't so straight forward, there's modelling for artists and posing at stag/hen parties. There are far too many options to chose from in shoot styles as it is, so why complicate it further?
Admin haven't gotten around to defining Dance and Cosplay in their article and there's so much overlap, just tell me what fashion model wouldn't pose in a wedding outfit for example? Or what is covered by Commercial: modelling cosplay outfits for a catalogue, posing nude for a skin care products manufacturer...Etc? I could go on but surely: Clothed, Swimwear, Lingerie, Topless, Nude and Adult are sufficient to define the types of work anyone is prepared to do? With Bondage, Dance and Fitness to highlight specific abilities.
