My rule of thumb is to dress like you belong there at wherever the incall is- blend in.
As for the ladies, the thought of Ginger in a babydoll and stripper-heels opening the door works pretty dam well.
The last time you met me in those short, sporty shorts and layered strap tops was really nice. You have great legs without heels. Your right out of the shower look in a towel was extra sexy also.
Since I have outcalls to my house, I have always told my first timers to just wear whatever they would wear as if they were going to the grocery store. Jeans, a top, athletic shoes. That way they look normal if a neighbor sees her drive up. Once she is inside, lingerie is a waste on me.
For outcalls, usually business or dressy casual, depending on if going out or going to a residence. For incalls, usually a matching bra and panty set, with stockings and heels, or body stocking, or whatever is requested. I like when P411 profiles specify what is preferred.
I like the idea that I'm getting something that I don't get at home. Heels and stockings for instance. Love it when the heels stay on. I had a couple of ATFs that used to wear the best lingerie...I apreciate the extra effort. Sadly one has disappeared and the other is now out of my budget and ia rarely in a city the same time I am.
