Many celebs seize the opportunity to go undercover on Halloween, but for these leading ladies, playing dress up is par for the everyday course:
1. Lady Gaga: From meat dresses to Marie Antoinette-worthy ensembles, there is always a trick up this performer's sleeve.
2. Nicki Minaj: It's not unusual to find this modern-day Rainbow Brite splashed in color or "wigging" out.
3. Jessie J: From barely-there to out there, the pop singer's unique ensembles are off the map.
4. Paloma Faith: There are few toppers this hat-hawking British performer hasn't tried.
5. Katy Perry: Whether covered in sushi or broken records, Katy never misses the opportunity to get in on the themed fun.
