Buy It Now at Brooklyn Fox, $89 and $45

"At least $100 would be safe for a set—a top and a bottom. Certainly you can do it for a little less and the sky's the limit if you want to do it for more. There are cute ways to get creative if your budget's not there; for example buy a set of three. Sometimes men will buy three thongs which can keep the budget under $50. The thing is, if you're going to spend less than $100 for a top and a bottom, it's probably not going to be the sexiest thing. It will be a more utilitarian style and that's not going to make anyone happy."
