Zoë Kravitz attended the "Big Little Lies" Season 2 premiere in New York and she wore a black Saint Laurent Fall 2019 dress. The entire cast looked great, honestly. I really liked Reese Witherspoon (Elie Saab) and Shailene Woodley's (Dior) looks as well. But I love a little black dress, especially a sparkly little black dress! So, Zoë is very deserving of the chicest starlet of the week.
