For me, I must say I appreciate when the escort goes to the trouble of being dressed when I first meet her. Doesnt have to be much at all, a simple pencil dress and heels is perfect or indeed just a fab pair of killer jeans and a nice top would be great.
I have no set views on lingerie so long as I dont feel like a complete eejit fumbling with the clasps trying to remove it, which happens regularly. I think escorts go to special shops which sell punter proof lingerie !!
Different figues probably suit different types of lingerie. I remember one escort, Viky, a czech girl who put on her lingerie when I was having my shower. When she walked into the room, I was literally blown away.
Naked too quick is a real turn off for me -- its a certain reminder of the business side of the arrangement and as such I find it a bit disrespectful to be honest.
