I may be showing my tenure here, but for a while this thread was always on the first page. 32 pages of people detailing their expectations and experiences with what would constitute a high dollar hotty (that term seems to have been rebranded as classy now). There may be some valuable information to mine from it.

A lot of people in this thread have the idea that the #1 rule of being a classy provider, is not calling yourself a classy provider! What is already understood need not be further explained. You just are! It's reflected in every post, every image, every interaction.
IMO, a high end provider is expected to be well mannered, cultured, manicured, articulate, engaging, and should have a certain air of professionalism. She should be someone who can blend in with her environment and know how to interact in different situations. I agree with you 100% and think how you brand yourself and handle your image is important as well. All of these are things that must be in place before a gentlemen even decides to step foot in your door. You can provide the best service possible once they meet you, at the nicest incall with all the amenities and niceties you can imagine, but if your ideal client isn't even making it to your door you may need to alter your marketing strategy. Some say that a true high class companion doesn't market herself at all, but only gains clients through private referrals, but I've never been with an agency so I can't attest to that.
I also think service plays a large role here. Celeste, you mentioned in a thread a while ago you were considering adding a home-cooked dinner option which I think is a phenomenal idea and really separates you from your peers. I personally am not a big cook, but I make it a point to go above and beyond for those gentlemen kind enough to spend their time with me repeatedly. If you strive to be the best at what you do and you treat your guest in a manner consistent with how you would treat your dream guy it is easy to be viewed as a true class act.
Just my .02 cents
