Alright, so this one hails from the wild world of Japan and is currently exploding all over the internet on both sides of the Pacific Ocean. 

The 'Virgin Killing Sweater', as its name implies is a sweater that doesn't leave much to the imagination. This fabled garment is full-length dress-sweater(?) that shows both front and back cleavage and it looks like something that comes straight out of a female character's wardrobe in an MMO 

Just a heads up...

This One is NSFW
