20 "Bad Blood" Costume Ideas

Yes, we already know what we are going to be for Halloween. Like, hands down, no questions — if you have a group of girlfriends you want to dress up with, you need to start deciding who gets to be which badass woman from Taylor Swift's "Bad Blood" music video. It's seriously the perfect costume idea for a big group of people because it basically means dressing in all black (which is flattering and hardcore), thigh-highs (ridiculously sexy), and various types of strappy/dominatrix-y hotness that we all not-so-secretly want to rock. No matter what you wear these for, it will be EPIC. Don't believe us? Just check out this girl gang's impressive getup.
