Taylor Swift: The Scholar's Approach by BringMoreLegos

Question 6

Much of 1989 purportedly chronicles Swift's relationship with ex Harry Styles. But a fellow student of the T[ayl]orah has suggested to me that another valid interpretation hints at an intense, on-again-off-again secret tryst with supermodel Karlie Kloss. A key piece of evidence is WHAT PHYSICAL FEATURE shared by Styles and Kloss, mentioned in such lyrics as "I Know Places" and "Wonderland"?
