This year's hottest Halloween costumes are ripped right from the headlines. A tongue-in-cheek "sexiest mom of the year" orange prison jump suit is a nod to the college admissions scandal. Plenty of other grown-up trick-or-treaters are channeling their inner Joaquin Phoenix by donning "Joker" costumes. Of course, he isn't the only scary clown out there. Pennywise from "It" is another popular costume this year. Want something positive? There's also a Mr. Rogers costume, complete with puppets.
