Welcome to the Sex Club

What to wear to a sex club? That's my dilemma as I stand in front of my closet looking for something not too brazen, not too demure. I've got a black bustier in here somewhere, but that would send the wrong message. I'm not out to partake, but to conduct research on what really goes on in one of the dozens of sex clubs that have cropped up across the country over the past few years.
