turtleneck leotard

A leotard with a turtleneck design.

The HeatTech leotard, which has a specific design, was originally known under this tag, but the ambiguity of the tag name led it to being populated by posts not referring specifically to the HeatTeach leotard, but to leotards with turtlenecks in general, hence the need for the separate tag (see Danbooru topic #21483 for the brief discussion).
