open-chest_sweater
An outfit that has gone viral from a user named Myako's tweet here on December 4th, 2014. The turtleneck ribbed sweater prominently features a cleavage cutout.
Artists eventually began throwing around the challenge to draw their waifu or husbando in the sweater.
Please note that sweaters with cleavage_cutouts are nothing new. Only use this tag if the sweater the character is wearing is identical/adapted from the one in the tweet or if the artist tags it open-chest sweater/says it is related to the whole fad.
Also called 例のセーター or that sweater as with the virgin killer sweater, although with limited use.
