I do 90% incall sessions, so I usually dress up in a nice lingerie outfit with matching thigh highs and heels unless I get a different clothing request.
That is what I feel sexiest in when I greet the clients at the door, and I just love playing dress up!!
Outcall I wear the sexy stuff under pants and a normal looking blouse or shirt. I dont need to be looking like a street walker and draw unneeded attention, that is just wrong, IMO.
