Meryl Streep and Nicole Kidman are going to the prom — sort of! The Oscar winning actresses showed off their characters’ shimmering costumes on the set of Ryan Murphy‘s The Prom, based on the seven-time Tony-nominated Broadway musical. On March 5, the two Big Little Lies actresses were seen on the Los Angeles set in effervescent costumes of sparkling sequins and fluffy cuffs! Nicole, 52, sported a bright green dress that shimmered and played up her blonde hair perfectly.
