“Abrasive” is probably an understatement to describe Sue Sylvester from “Glee.” I can never get tired of this gym teacher’s screaming insults through her ever-present megaphone. Having an excuse to be mean is the best way to spend a Hallow’s Eve. Just find your annoying roommate sometime during the night and say everything you’ve been bottling up for the last year. Then say that you take Halloween very seriously.

Get the look: Jennings says actress Jane Lynch clearly has never done Botox as she is chock full of expressions. Her furrowed brows and laugh lines are a must-do with this look. Using a similar technique for the Betty White costume, if you’re younger than your 40s, you want to age your face. Jennings also says Lynch doesn’t have the smoothest of skin. To manipulate her skin tone, take bits of Kleenex tissue and glue them onto your face with eyelash glue. Then stipple foundation right over it. Do this all over your face. Use minimal makeup, and top the look off with a shaggy blonde boycut wig, an Adidas track suit and a megaphone.
