How many providers are willing to dress up for the date? Say sexy business woman, or school girl, or whatever..  Who considers this part of the donation and time, and/or who is willing to do this for an extra $?   ..it can even be as simple as wearing the fishnets or stockings that the man requests.  Im asking because im wondering if this is normal to ask this kind of request or not.
 thanks!

Most gals will wear what you ask for providing it is with in reason. Keep in mind that traveling ladies don't have a wardrobe trunk at their disposal.

If you want an outfit that is very specific you should be prepared to buy it for the lady and present it as a gift at the start of the appointment.

As always the best way to go about this is to ask the lady in question.
