The Riverdale Girls Get Nerdy!

The ladies who starred in the comic book inspired CW series Riverdale for the last 7 years got together this weekend to celebrate Halloween together and it looks like they kept the nerdy comic book inspiration going by dressing up as three different Gotham city characters.

Madelaine Petch used her natural red hair to dress up as Poison Ivy with Camila Mendes who dressed as Julie Newmar's version of Catwoman and Lili Reinhart slipped into a tight latex suit as Harley Quinn.

The ladies posed together for a quick photoshoot before heading out into the night to party and shared the looks with their fans on Instagram, gaining millions of likes over night!
