Spandex fetishism is a fetishistic attraction to people wearing stretch fabrics or, in certain cases, to the garments themselves, such as leotards. One reason why spandex and other tight fabrics may be fetishised is that the garment forms a “second skin,” acting as a fetishistic surrogate for the wearer’s own skin. Wearers of skin-tight nylon and cotton spandex garments can appear naked or coated in a shiny or matte substance like paint. The tightness of the garments may also be seen as sexual bondage. Another reason is that nylon-spandex fabric (preferred by many spandex fetishists) is often produced with a very smooth and silk-like finish, which lends a tactile dimension to the fetish – as well as a visual one. There is a sexual attraction to leotards and other dance related clothing. This also goes for gymnasts too.
In comic books, superheroes, superheroines, and supervillains are generally depicted as wearing costumes made of spandex or a similar material. The superheroines always wear skintight, very flashy and bright-coloured costumes that usually cover only just enough of the body to be presentable. Fantasies involving superheroes or the wearing of superhero costumes are commonly associated with spandex fetishism.
Full-body suits called zentai entirely immerse the wearer in skin tight fabric. The suits are essentially catsuits with gloves, feet, and a hood. The wearer experiences total enclosure and those who enjoy erotic objectification might make use of the garment’s anonymizing aspect. The word zentai means whole body in Japanese.
