ok, the main thing is just to wear something that shows that she is expecting it. It doesn't have to be fancy lingerie, but could just have some lace or whatever. Also, having her hair done right would be a turn on.
Nice sexy undies and if you can expensive undies, if you can include black glossy stockings or silk, this look is always sexy. If you are going out wear it with a tight pencil skirt with a slight split, just enough for him to notice or catch a glimpse that you are wearing stockings. That will be enough for him to not be able to concentrate for the rest of the night.
I'm a little girly,as they say and I am bi,so I do happen to have that double sided view.I think that a woman looks her most sexy and confident when she looks like a woman.By that I mean,put on a nice skirt or dress,some great heels.For undies,how do you beat a sexy victorian corset,gorgeous vintage nylon stockings and a short silky robe and a pair of killer heels,or even some fluffy mules or slides.You'll knock'em (or her) dead!
