10 Best Dressed: Week of August 14, 2017

As summer quietly winds down, the week’s most stylish opted for totally offhand opulence. Call it the new low-key louche. HRC wore a breezy caftan to a wedding. . . and won the prize for best dressed guest. Elizabeth Olsen and Naomi Watts made the case for the little white dress—loads of volume but otherwise a total blank slate. Chloë Sevigny went tailored and micro. Emrata wore a Versace shirt as a dress. And Zendaya and Sienna Miller gave new life to the evening pajama as red carpet wake-up call.
