Missa, I got real nice mermaid tails from
http://www.the2tails.com/ for myself and my partner. We used them at Fetfest and Fusion (BDSM camps) and they were a huge hit. I knew she would get alot of attention as a mermaid, but I was surprised how many ladies loved a merman, lol. They are also ok for vanilla events. She charged people 20$ for like 15 minutes of swimming with her pink tail at a hotel pool in vegas! Thing paid for itself like 5 times over.
