Another color piece from my "long torso era". Petina rather enjoys swimming which is a somewhat rare hobby with mice http://www.furaffinity.net/view/1123734/ and seems to rather enjoy playing the mermaid game. As general rule the mermaid suits fall into two categories. 1. exercise suits, these are suits that permit vigorous swimming and movement http://www.furaffinity.net/view/1972506 . These also include the little sea lion outfit that she wears on occasion. http://www.furaffinity.net/view/1616206/. 2, are suits designed for more relaxed underwater enjoyment. the suit and tail are not as optimized for locomotion and are often more decorative in nature. Also suits can be split by whether they encompass the mouse's tail or leave it free floating. Here is an example of a type 2 suit with a free tail design. Petina seems to be quite happy with it.
