Edie Sedgwick is widely thought to be Dylan’s song subject

Evidence

Edie is widely imagined occupying a central role in Dylan’s personal mythology, the supposed subject of three songs from Blonde on Blonde (“Just Like a Woman,” “Leopard-Skin Pill-Box Hat,” and “One of Us Must Know (Sooner or Later)”) as well as the unreleased “She’s Your Lover Now.” — J. Hoberman, Everything Is Now, 1937
