Katy Perry never fails to disappoint with her costumes whether it's onstage (remember her infamous cupcake boobs, anyone?) or off, and her costume for Halloween this year was no different. Perry and her BFF, actress Shannon Woodward, nailed the look of vintage MTV star Daria and her BFF, Jane Lane.

The two attended a party at the Hollywood Cemetery in Los Angeles before heading to another party in Los Feliz. Well done, ladies, well done.
