I wear jeans and an untucked button-up as if I'm headed out on a casual date. There's as much fun in taking off clothes.
What should she wear to the outcall? Something nice that doesn't draw attention. I once had an outcall date midday on a weekday at a nice hotel. I was meeting her for the first time. When I opened the door, she was towering in height (easily 6'3" with the heels) with a protruding belly. But that didn't stop her from wearing a very tight dress that had a very short skirt. If I had to get her from the lobby, I'd have gotten down there saw her and start walking into walls like I just remembered I'm actually Stevie Wonder. JFC, she was embarrassing.
