Perhaps they need better Press Agents. Only very clueless neonates or truly stupid creatures would pretend to be Artistes when they couldn't draw a stick figure without a ruler. Toreador Poseurs don't try to be something they aren't. They do have the style and taste and aesthetic sense of the Artiste, but they haven't the skill or don't want to make the effort. They much prefer the pursuit of beauty to the actual creation of it.
Poseurs actually are artists, but of much less obvious arts.
A Poseur creates her reputation through holding exquisite parties, having a fine personal art collection, showing off a fashionable haven or two, grooming a herd of talented Artistes, and a myriad of other actions that display her exacting standards and elevated tastes. It is born or learned, not posed. Poseurs are in many ways the quintessence of the Toreador Clan weakness. They are completely enraptured by beauty and cannot escape its draw. They surround themselves with beauty in whatever forms that suit them.
