Clothing is not an option - Ressorts for real Naturists only ?
To my knowledge:
- Lake O' the Woods (IN)
- Bare Oaks (Canada)
- Lake Como (Florida)
The concept of "nude-mandatory" is a bit nebulous since some of these resorts still allow for coverage in some circumstances (protection, newbies); and covered up people are not forced/requested to "take it off." It's more a philosophical stance of "embracing staying nude", that is accepted and practiced by the majority of its attendees.
At my resort, for example (LOTW), the majority of people there will get naked in the parking lot, and not cover up again until it's time to leave. That is certainly also the case for my wife and myself; as well as our friends and acquaintances. It's just a different vibe when we're all naked - while socializing, doing activities, eating, etc... But that doesn't mean there aren't any allowances for people who choose to take a short break from being naked all day. A lot of the misconception about "nude-mandatory" is from people who think it means people are "forced" to be naked all day.
