I fully accept what you say but the criteria has to be different for glamour model purposes.
When the purpose of the photoshoot is to highlight the beauty of a particular garment, it cannot afford to be camouflaged by other garments of a similar colour. You can usually get away with it in the case of any other colour but black always creates too many shadows. Colour contrast plays an important role in this type of work.
Anyway, to put your mind at rest, I shall not mention it again.
