Does anyone know what a Hautekoko Party is? I have never heard of this. From reading the invitation, it left me confused. Or maybe I'm reading into it since I have no clue what it is? It made me feel old . . . I used to know all the party themes

BTW, Google and Wikepedia weren't any help.
Anyway, the invite came from an acquaintance and no, I haven't asked directly. The invite said the following:
"_____(name of host) would like to invite you to a night filled with fun and excitement. So if you want a little adventure and would like to add some accessories to your love life, you don't want to miss this party. So... leave your work behind and bring the right woman to the bedroom OR gentlemen who are attending, bring the right man to the bedroom. You must be at least 18 years old to attend. Attire for women: cocktail dresses. Attire for men: Business casual. Also, at this party, we don't use our real names. You need to have a bedroom name for the night. The most creative name wins a free gift."
Any thoughts on what this invite is all about?
