high heels and a smile (but not those Herman Munster style massive platform heels as worn in this thread, by a young lady on a bed)....
Actually, I prefer the a lady is dressed as she would be going out with friends for a cocktail.... 4' non-stripper style heels, nice fitting jeans, maybe a tight wife-beater type of t-shirt (sans bra), with maybe a nice v-neck sweater - casual-classy sexy is hot, IMHO
