Given what I'm noticing about the WAM community in the United States, we are very spread out with very few people within close proximity to have meetups.
Speaking specifically about wetlook, we know that most public pools won't let us swim in our clothes and it's hard to get that rule changed. I have an idea similar to the "Phat Dippin" video that came out years ago.
I recommend that we get together and host a big wet clothes weekend for all of us. A group of us could rent a pool and have an itinerary for a beach and/or a lake day along with plenty of time at our main pool. All outfits are welcome and nudity will be prohibited. For those who are comfortable, we can take photos and videos and send it to news media to spread our fun idea.
If people see us happy in wet clothes, that'll be a great start to changing the culture in the US. All it takes is for us to get together and organize the event.
