Whenever Taylor Swift gives fans a new song and video, she pairs it with a new aesthetic and concept, which, of course, makes for perfect Taylor Swift Halloween costume ideas. Taylor Swift “The Fate of Ophelia” from The Life of a Showgirl costume If you don't want to go for face value and tap into the showgirl aesthetic outright, channel your inner Ophelia (Taylor's version, of course) with a simple frilly dress and a wig or your own hair done up similar to Swift's at the beginning of the music video for “The Fate of Ophelia."
