Apparently, this is a top. It is not, as I erroneously thought, the shredded corpse of a top.
My best guess is that Forever 21 is trying to draw in teenagers by subtly reminding them of werewolves, and subsequently, the Twilight series. Although, that’s a pretty big gamble, because you run the risk of alienating all the girls who aren’t on Team Jacob.
Personally, I’m on Team Phillip, but that’s because I like my men with a healthy fear of fire, and green’s totally my color.
