I’ve been to three or four Dare to Bares, by memory.
To back up what Thincut said… it was surprising how few people were going without a towel. So, there doesn’t seem to be a massive difference in “vibe” whether you go to Dare to Bare or one of the other nights (unless I was just “unlucky” the times I turned up, I guess)
I just tend to walk around with the towel around my shoulders even on the non-Dare to Bare nights. So that folks can get a clear enough look of the “goods” if they so wish, lol
