Sienna Miller has posted exactly once on Instagram, back in 2017, but somehow she still amassed more than 873,000 followers. Such is the public’s fascination with everything this English-American actress does, says, and wears. In the 2012 film The Girl, she captured the appeal of Tippi Hedren; in Ben Affleck’s period drama Live by Night (2016), she played a gangster’s mistress; and now the decidedly downtown New Yorker appears as the privileged wife of a badly behaving politician in the new Netflix drama Anatomy of a Scandal. Here, Miller shares her key components to the good life. —Ashley Baker
