My daughter had been sucked in with mermaids well before she went to a fairy festival and saw a woman swimming about as a mermaid. From that moment, she wanted a tail for herself. She began by earning a monofin, so that she could swim as if she had a single flipper. Over the swim season, my wife challenged her to qualify in the butterfly, as that swim stroke used a mermaid-like kick. My daughter did so, and as a result, is now the owner of a mermaid tail.

Those mermaid tails are wicked cool. Hers is this iridescent green, with a vaguely scale-like pattern on it. The thing fits her like a glove (presumably so that it won't fall off in the water.)

Hey, wait a minute, my daughter is cos-playing. Whohoo.
