I've never lost my suit of my ankle, but do try to be vigilant in making sure I can 'feel' its presence. I hope I never get into q situation where it feels it's there even if it no longer is.
The other option is to pick a quiet moment when I can leave the door on the beach, perhaps behind a rock or a shrub, and stay in the water until there's another quiet moment for me to exit. Funny how often my section of the beach becomes busy with walkers just as I feel it's time to come out again!
Did lose my swimsuit once while swimming in Long Island Sound . Was staying with my parents. Had dropped it down to my lower legs . Didn't realize it slipped off me until it was gone . I was swimming after dark . Found it on the shoreline the next day . Did have a beach towel so could cover up getting back home . Now I will always have it wrapped up around my upper arm , where it can never be lost .
When I was in my early 20s, I would skinny dip at a crowded city beach. I would wade out until the water was up to my neck and then I would slip my swimsuit off. I never tied it to my body. I just held it in my hand. The downside was that made it difficult for me to swim. Also, I needed to be careful that I didn't lose grip of my suit. I did have regular shorts by my towel that I kept near the shore so, worst case scenario, I had something to put on.
