Once upon a time, etiquette was important: One needed to know which fork to use, which glass to sip from. Those days, my friends, are over. Now, questions of etiquette mainly revolve around how many Instagrams each guest is allowed to take during dinner.

But there remains one corner of the world where table etiquette remains a vexing and important issue: at nude resorts. And it’s a problem for a growing number of people.

“We’re seeing a rise in ‘nakations,’ especially among people in their thirties,’” says Sue Nerud, spokesperson for the American Association for Nude Recreation. Exact statistics are hard to come by, however, since many nudists prefer to remain anonymous. (In fact, several nudists in this article spoke only on the condition their names not be used.) And while Nerud said recent studies show that nakations are great stress relievers, there remain those pesky etiquette issues—which we are about to solve for you.
