In the series Keroro Gunso, aliens use Pekopon suits to disguise themselves as Pekoponians.
There are several versions of the Pekopon Suit. They include a business suit, a high school cheerleader, and a schoolgirl. There is also a special version used in Episode 50 called the Aki Hinata version, which includes Aki's ponytail placed on Keroro's head when he wears it. In episode 320 the Keroro Platoon used a special version where they controlled human robots as part of an invasion plan involving Natsumi Hinata.
