The 'Virgin-Killing Sweater' (Doutei wo korosu seta) refers to a style of sleeveless, backless turtleneck sweater that gained massive internet notoriety in early 2017. Originating from Japanese social media, the garment earned its provocative name because of its revealing design, which was jokingly said to be 'lethal' to inexperienced young men. The meme exploded across the global art community, with thousands of artists drawing their favorite fictional characters wearing the knitwear. Beyond fan art, it has become a staple of internet fashion culture, often used to satirize revealing trends or to highlight the contrast between a character's personality and their bold outfit choice.
