Is Monterey's latest bash a decades costume party? It certainly looks like it! On Monday, Reese Witherspoon and Nicole Kidman were spotted wearing their best retro wear as they filmed the upcoming second season of HBO's Big Little Lies. While Nicole, aka Celeste Wright, sported a technicolour coat and matching pink boots reminiscent of the '70s, Reese, who plays Madeline Martha Mackenzie on the series, looked like an '80s Barbie doll with teased hair and an all-pink outfit. Seriously, the resemblance is uncanny! As you patiently wait for the upcoming season, see some of the most recent set pictures ahead.
