I love seeing ladues wearing

Low cut blouses
Leotards and tights
Tight fitting jeans
Tight fitting skirts
Short skirts

I also like

Seeing the outline of the nipples beneath a top
The way a tight skirt looks
And, dresses that give just a hint of what's underneath when the light is behind them.

But most of all, I think, a warm smile is really a turn on for me. Don't know that the smile actually makes me honry, but it certainly captures my attention.

Probably more, but these came to mind
