Trope-a-Day: School of Seduction

School of Seduction: The Circle of Silken Flowers (see: Platonic Prostitution, Band of Brothels) has its Velvet Academies (which concentrate just as hard on the arts of the salon and many other required topics, of course), and so forth.  Rather classier, I suspect, than most of the examples given; after all, these are professional organizations with an emphasis on quality.
